2. Marks the debut of Carl "Crusher" Creel aka The Absorbing Man in live action media. Although in Hulk (2003), Bruce Banner's father gained a similar ability.
3. In the park Creel picks up a ball and chain, that is his weapon of choice in the comics.
4. The character of Lance Hunter is introduced as a mercenary working with former S.H.I.E.L.D. agent Hartley. In the comics, Hunter is the leader of S.T.R.I.K.E., a British intelligence agency similar to S.H.I.E.L.D.

9. After Agent Carter and The Howling Commandos take down the last Hydra site (that they know of), one of the Commandos attempts to open a crate containing a confiscated artifact, and Agent Carter quickly closes it. Before it closes, however, there is a brief glimpse of a blue body. It is the body of a Kree, most likely the body of the "guest host" used to develop the GH-325 serum.
10. Costume designer Ann Foley revealed in the book Agents of S.H.I.E.L.D.: Season Two Declassified that the imaginary Simmons wears the same outfit she wore in Agents of S.H.I.E.L.D.: FZZT (2013). Normally the character never wears the same outfit twice, so this outfit is a clue to her being a figment of Fitz's imagination.
11. The location Talbot gives Koenig is "Sierra-Victor-Niner." "Sierra" ( Dichen Lachman ) and "Victor" ( Enver Gjokaj ) were characters on Joss Whedon's previous show Dollhouse (2009). In Agents of S.H.I.E.L.D. Lachman goes on to play Jiaying, Gjokaj goes on to play Daniel Sousa.

Face My Enemy

1. For the May vs Agent 33 fight sequence, stunt performer Samantha Win wore a tight fitting sequin dress as 33 and Tara Macken May's lingerie.

A Hen in the Wolf House

1. The Hydra research base appears to be located in Pittsburgh, PA. When Jemma Simmons and Bobbi Morse jump from the rooftop to land on the Quin-Jet, the skyline appears behind them. At least four buildings in that shot match ones from the Pittsburgh skyline.
2. There's a brief reference in one scene at the Hydra lab of a comic book character named Bessie the Hellcow
3. Both Adrianne Palicki and Cobie Smulders (Maria Hill) have portrayed the DC Comics character Wonder Woman: Adrianne had done so for the aborted live-action Wonder Woman (2011), while Cobie had voiced her for The Lego Movie (2014) and had also been attached to a proposed live-action film written by Joss Whedon.

10. The offices of S.H.I.E.L.D. of this episode are the same offices of the SSR (Strategic Scientific Research) where the series Agent Carter (2015) is set. You can also see the SSR coat of arms hanging on the wall.
11. Raina (Ruth Negga) meets Phil Coulson (Clark Gregg) at a restaurant called La Comtesse Furieuse. This translates from French to be 'the angry countess,' and could just as easily refer to Raina as to Bobbi Morse (Adrienne Palicki), whose identity is revealed in this episode

A Fractured House

1. In the Marvel Comics Marc Scarlotti is known as the villain Whiplash. In this episode he is renamed Marcus Scarlotti, and is a Hydra Agent who wields a whip-like weapon in battle.
2. This episode was supposed to be the debut of the Avengers: Age of Ultron (2015) trailer, but it leaked first. However, new footage was released together with the trailer.
3. Senator Ward unveils his anti-S.H.I.E.L.D. plan on WHiH News, the network that covered the 2011 Stark Expo in Iron Man 2 (2010) and the battle at Culver University in The Incredible Hulk (2008). This fictional news network later became a web series serving to promote the latest entries in the Marvel Cinematic Universe: WHIH News Front (2015).
4. The relationship between Grant and Christian Ward on the show is similar to the relationship of Simon and Eric Williams in the comics. Simon inherits the family corporation and is loved by everyone around him just like Christian Ward. Eric becomes the evil brother who then gains the super villain name Grim Reaper.
5. In the safehouse in Bruges, Hunter offers a 'Straffe Hendrik'; a local brew he found in the area. Straffe Hendrik is indeed one of the many brews Bruges has to offer and has been exported to different countries for years. Its original brewery is still there, which means, if Hunter was telling the truth, the safehouse is located in the center of Bruges close to the river Reie.
6. Bobbi Morse is wearing a Star Wars T-shirt while informing her colleagues about the Attack on the United Nations. Both Marvel and Star Wars are Disney properties.
7. The title appears designed to evoke the Biblical "house divided against itself" image, reflecting the condition of S.H.I.E.L.D. post the HYDRA betrayal, and the inability of the Ward clan to get on the same page.
8. "A Fractured House" originally aired on ABC on October 28, 2014, and according to Nielsen Media Research, was watched by 4.44 million viewers.
9. Coulson questions the presence of a Grumpy Cat mug in the base kitchen. In Agents of S.H.I.E.L.D.: One of Us (2015) the mug is revealed to belong to Fitz.

The Writing on the Wall

1. Skye mentions receiving information from a contact named Micro, "a bit of a crime enthusiast." This is arguably a reference to the Marvel Comics character David Linus "Microchip/Micro" Lieberman, an ally/friend of Frank Castle, A.K.A. The Punisher.
2. Ward mentions "Strucker". Baron Von Strucker is one of Hydra's heads and currently in possession of Loki's staff. He made his debut in the mid-credits scene in Captain America: The Winter Soldier (2014) and returns in Avengers: Age of Ultron (2015).
3. In the comics, Cameron Klein is the grandson of Stanley Klein, one of the Howling Commandos.

7. "The Writing on the Wall" originally aired on ABC on November 11, 2014, and according to Nielsen Media Research, was watched by 4.27 million viewers.
8. The Blue alien is said to have been thousands of years old, which could foreshadow the Inhumans, a group of Homo Sapiens who were experimented on by blue aliens called the Kree, thus given powers.
9. This episode marked the end of the mystery behind Coulson's resurrection.
10. At about 9:38 Fitz makes a clever wordplay. He says "Corpsey Diem", leaning on to the meaning of the Latin aphorism "Carpe Diem".

The Things We Bury

1. Bobbi Morse makes a reference to the MKULtra trials. These were experiments carried out illegally by the CIA to figure out ways to control the mind when interrogating someone.
2. The son of Lou Ferrigno, Lou Ferrigno Jr., plays the HYDRA sleeper agent who released Whitehall from "The Rat". Lou Ferrigno (Sr) is best known as a bodybuilder and the actor who played the Hulk in The Incredible Hulk (1977)
3. Bobbi mentions that Bakshi has "got that whole classic Bond-Villain thing going on." Simon Kassianides, who plays Bakshi, appeared in the Bond film Quantum of Solace (2008).

Ye Who Enter Here

1. The sequence where Coulson and Bobbi Morse arrive in Puerto Rico was actually filmed in the island's capital, San Juan.
2. The title comes from the original English translation of Dante's Divine Comedy, specifically the inscription over the gates of Hell - "Abandon All Hope, Ye Who Enter Here".
3. The side of the building used during Raina's attempted to escape Skye is actually the building used in Who Framed Roger Rabbit (1988). Although the inside of the building was not filmed, the front of the building facade was used as Eddie Valiant's office. The address is 1130 S. Hope Street, Los Angeles, CA 90015.
4. "...Ye Who Enter Here" originally aired on ABC on December 2, 2014, and according to Nielsen Media Research, was watched by 5.36 million viewers.
5. Raina reveals the "Blue Angels" to be alien Kree who chose a selected few to inherit Earth. This refers to the origins of the Inhumans, where the Kree came and experimented on certain humans, who then experience Terrigen mist-gained power.
6. The music box in Skye's dream is playing the chorus of the song "Bicycle Built For Two." Those lyrics - 'Daisy, Daisy, give me your answer, do' - foreshadow the revelation of Skye's being Daisy "Quake" Johnson.
7. Skye is wearing a flower dress in her dream, foreshadowing her link to Raina.

What They Become

1. Skye's father calls her "Daisy". This is a reference to SHIELD agent Daisy Johnson who also goes by the superhero Quake in the comics.

4. Lady Sif from Thor (2011) and Thor: The Dark World (2013) makes her second appearance in the series.
5. The scene in which Vin-Tak is captured was filmed on the location used for the entrance to the Batcave in Batman (1966).
6. A Crossfire-Maximum Paintball arcade game is present in the SHIELD base. This game was released by Team Play in 2005 and is considered hard to find by collectors.
7. During their training session, Skye asks May if she wants her to go full "Mortal Kombat" on her. Ming-Na Wen actually played fighting game character Chun-Li in the live action movie Street Fighter (1994). The Street Fighter video game is similar to - and came out around the same time as - the original Mortal Kombat game.
8. Jaimie Alexander the actor who plays Lady Sif also plays Jane Doe in Blindspot (2015) a woman who also loses her memory.
9. "Who You Really Are" originally aired on ABC on March 10, 2015, and according to Nielsen Media Research, was watched by 3.80 million viewers.
10. When Skye says the man she fought turned blue like he just tried some Willy Wonka gum, this is a reference to Roald Dahl's 1964 novel Charlie and the Chocolate Factory, first filmed as Willy Wonka & the Chocolate Factory (1971), in which Violet Beauregarde tries an experimental chewing gum, swells up into a sphere, and turns blueberry blue.

One of Us

1. Part of this episode is set at Culver University. Culver University is where Bruce Banner Hulked out in The Incredible Hulk (2008).

Love in the Time of Hydra

1. It is revealed that Lola is not just the name of Coulson's 1962 red Corvette, but also an acronym which stands for Levitating Over Land Automobile.
2. Skye says she has ended up on the "DL" and has to explain that this means "disabled list". At the time of the first broadcast, this term was used by Major League Baseball for players who were injured and temporarily removed from the roster. It was unique to MLB, in that all other sports leagues used the term "injured list", and MLB changed to using that term in 2019. To know this term and use the common shorthand abbreviation "DL" indicates that Skye is more than a casual fan of baseball in the US.
3. "Love in the Time of Hydra" originally aired on ABC on March 24, 2015, and according to Nielsen Media Research, was watched by 4.29 million viewers.
4. Kirk Acevedo plays Agent Calderon, who works for Robert Gonzalez, played by Edward James Olmos. Olmos played Lt. Castillo on Miami Vice (1984). In that series, the original villain was named Calderone, but that was before the arrival of Castillo.
5. The episode's opening scene in the diner contains references to the opening diner scene in Pulp Fiction (1994). Ward orders pumpkin pancakes (the name of Tim Roth's character is Pumpkin), and in the later episode Agents of S.H.I.E.L.D.: S.O.S. Part 1 (2015), Ward uses the term "honey bunny," which is the name of Amanda Plummer's character. Ward and Agent 33 pull their guns at the same time and start yelling like the couple in Pulp Fiction. When they corner the doctor, he pulls out his wallet and offers it to them. In the film, Pumpkin and Honey Bunny go around collecting all the diner patrons' wallets, including Jules Winnfield's (Samuel L. Jackson's) "Bad Mother Fucker" billfold. In the MCU, Samuel L. Jackson plays Nick Fury, former director of S.H.I.E.L.D.

One Door Closes

1. The safe-house Skye is held in was built by Bruce Banner. A hole can be seen punched in a wall. Steve Rogers also stayed there after being de-frosted. However, it is not the same cabin that Banner was seen in at the very end of The Incredible Hulk (2008) as at that time he was still on the run and not in a position to design protective walls with help from S.H.I.E.L.D.
2. This episode contains several flashbacks to the day S.H.I.E.L.D. fell, making them take place during the events of Captain America: The Winter Soldier (2014) and Agents of S.H.I.E.L.D.: Turn, Turn, Turn (2014).
3. One of the lockers in the locker room has the name Mimikakis written on tape on it. Lanie Mimikakis worked in the art department on the series.
4. Lucy Lawless and Edward James Olmos previously appeared together as enemies and later as allies in Battlestar Galactica.
5. This is the fourth episode in which Agent Weaver makes an appearance in the series. It is the second time in Season 2 of the show, her first time being in Agents of S.H.I.E.L.D.: Seeds (2014).
6. "One Door Closes" originally aired on ABC on March 31, 2015, and according to Nielsen Media Research, was watched by 4.26 million viewers.
7. Despite Bobbi telling the agents to only use icers when they land at the safe house, none of the weapons shown have the distinctive barrel that are used to identify the non-lethal ammunition that they contain. In addition, regular gun sound effects are heard when the weapons are fired instead of the distinctive "icer" sound effect. This indicates that Bobbi was the only one who believed that capture was the intent of the mission.
8. In a flashback to the day S.H.I.E.L.D. fell, Hartley mentions that "Vic [is] going to hold the Hub." Viewers of the first season know that Victoria Hand secured the Hub with the capture of John Garrett and elimination of the Hydra agents.

Afterlife

1. In Agents of S.H.I.E.L.D.: The Things We Bury (2014), Cal told Whitehall that he wanted to reunite with his family in the "Afterlife". This episode revealed that he was talking about the Inhuman's sanctuary in China and not the life after death, literally.
2. When Fitz is packing his stuff, he down a selfie of himself and Simmons taken at the Incan Archaeological site in Llactapata, Peru in season one's Agents of S.H.I.E.L.D.: 0-8-4 (2013).
3. The battering ram sequence showing the door integrity at the cabin plays out much like a sequence in Captain America: The Winter Soldier (2014) when Nick Fury is cornered by Hydra Agents. The battering ram was used on his vehicle.
4. Fury's toolbox has an outer layer of vibranium, the same material Captain America's shield is made of.
5. The license plate on the jeep that Hunter and Coulson stole was from South Carolina. This was a nod from writer/producer Craig Titley to the state, where his best friend works as a professor at Lander University. Titley travels to South Carolina every year for the Lander University Film Festival where he acts as a judge and guest speaker.
6. Before the siege on the cabin, Coulson pulls a deck of cards from an old Howlers kit. This is likely a reference to Robert 'Rebel' Ralston, one of Nick Fury's Howling Commandos in the comics, who never loses at poker.
7. Coulson mentions he had Deathlok keep tabs on Doctor List in the last 6 months. This places that assignment in between episodes 3 and 4 of this season.
8. Hunter mentions "going down like Butch and Sundance", Sundance was played by Robert Redford who played Alexander Pierce in Captain America: The Winter Soldier (2014).
9. "Afterlife" originally aired on ABC on April 7, 2015, and according to Nielsen Media Research, was watched by 4.24 million viewers.
10. This episode features the return of Mike Peterson/Deathlok.
11. Lincoln is introduced in this episode.

Melinda

1. In the first flashback, which takes place around 2008, Agent May mentions that S.H.I.E.L.D. is putting every dime into the construction of the Triskelion, as seen in Captain America: The Winter Soldier (2014). However, at the beginning of Ant-Man (2015), the Triskelion was already under construction, and that sequence took place in 1989, so she was probably referring to the addition of the underground hangars and the three Helicarriers for Project Insight (also seen in The Winter Soldier).
2. Skye's birthday is revealed to be July 2, 1988. At this, Skye realizes that she's 26, setting this episode in late 2014 or early 2015 (likely early 2015, given the airdate). Chloe Bennet was four days shy of 23 when the episode premiered.
3. "Melinda" originally aired on ABC on April 14, 2015, and according to Nielsen Media Research, was watched by 4.04 million viewers.
4. This episode reveals that Raina ( Ruth Negga ) has precognitive, clairvoyant dreams. This is fitting since she spent most of season one hoping to meet The Clairvoyant so she could find out what she would become after terrigenesis.
5. Coulson is technically not in this episode until the very last scene. The rest of his appearances are only in flashbacks.

Frenemy of My Enemy

1. This episode along with Agents of S.H.I.E.L.D.: The Dirty Half Dozen (2015) takes place before the events of Avengers: Age of Ultron (2015).
2. The title is a play on the phrase "The enemy of my enemy is my friend", meaning that people can set aside their differences and work together when they are fighting a common enemy. In this case, the "enemy" is HYDRA, and the "frenemy" is Ward, since he used to be HYDRA but is now at odds with them.
3. "The Frenemy of My Enemy" originally aired on ABC on April 21, 2015, and according to Nielsen Media Research, was watched by 4.45 million viewers.
4. Skye's real name is revealed to be Daisy Johnson, a character better known in the Marvel Comics as Quake.

The Dirty Half Dozen

1. The base Lincoln and Mike are held captive, is the same base Quicksilver and Scarlet Witch have been experimented on during the Captain America: The Winter Soldier (2014), mid-credits scene.

5. "The Dirty Half Dozen" originally aired on ABC on April 28, 2015, and, according to Nielsen Media Research, was watched by 7.24 million viewers within a week of its release.
6. The twins that Dr. List mentions in the facility are the characters shown in the same cells holding Mike and Lincoln during the mid-credits scene of Captain America: The Winter Soldier (2014), are characters properly introduced in Avengers: Age of Ultron (2015), which came out the Friday following the original air date. Their names are Pietro and Wanda Maximoff, known as Quicksilver and Scarlet Witch respectively.
7. The scene where Skye takes out a room of Hydra agents was all done in one shot by Chloe Bennet with no stunt doubles. She fractured her elbow in two places during the take.
8. It is mentioned that the "Theta Protocol" concerns The Avengers. In the opening scene of Agents of S.H.I.E.L.D.: Scars (2015), it is revealed that the Theta Protocol is actually the building of a new helicarrier to support the Avengers, which is eventually used in Avengers: Age of Ultron (2015).
9. In the rescue mission, Coulson had the hidden mission of gathering Hydra intelligence. This mirrors the opening scene of Captain America: The Winter Soldier (2014), where Black Widow was to gather intelligence while the rest of the team was rescuing hostages. The intelligence that Coulson gathers reveals the location of Loki's scepter in Sokovia, and lead directly into the events of Avengers: Age of Ultron (2015). Raina also has a vision concerning the events of the movie, including the scepter.

Scars

1. Helicarrier 64, which is featured here, is the same one that appeared in The Avengers (2012) and Avengers: Age of Ultron (2015).
2. The final exchange between Gonzalez and Jiaying illustrates two competing philosophies- government control for perceived safety as espoused by Gonzalez vs individual freedom from intrusive government as espoused by Jiaying. In the Marvel universe, a similar discussion was seen in Captain America: The Winter Soldier (2014) when Captain America told Director Fury the helicarriers were like holding a gun at everyone on Earth and calling it protection and that it wasn't freedom, but instead fear. While he exists in a different universe, a similar scenario was seen near the end of Man of Steel (2013) when Superman destroyed a government surveillance drone.
3. Alicia Vela-Bailey plays the Inhuman called Alisha. She has also served as Adrianne Palicki's stunt double since Palicki joined the cast.
4. The post-it on Sam Koenig's mirror says: "CALL YOUR SISTER!!!"
5. This episode takes place after the events of Avengers: Age of Ultron (2015).
6. The portal stone left behind by the Kree was being held on the S.H.I.E.L.D. carrier in room number 47. Marvel One-Shot: Item 47 (2012) is a Marvel One Shot film short about a Chitauri weapon which was left behind in New York after the battle at the end of The Avengers.
7. Sam and Billy Koenig briefly reference Call of Duty at the beginning of the episode when they mention "spawn kills" and "Black Ops".
8. Sam is seen sleeping in Star Wars sheets. Sam is played by Patton Oswalt, who is the narrator of The Goldbergs (2013), voicing the character of Adam, who sleeps in Star Wars sheets.
