The Writing on the Wall (Agents of S.H.I.E.L.D.)

A man is invited to a young art teacher's apartment one night, where he reveals alien designs tattooed all over his body. He assures the young woman that they have met before, and pulls out a knife to help her remember. The woman, Janice Robbins, was once a S.H.I.E.L.D. agent, and in crime scene photos Agent Skye shows Director Phil Coulson, her body has been carved with the alien symbols. Coulson and Skye search her apartment and find many paintings she had made of the symbols. Agent Jemma Simmons performs an autopsy on the body, and discovers that both the victim and the killer had the GH-325 drug in their blood. Coulson believes the only way to get answers is to use Hydra's memory machine on himself, knowing that doing so would be like torture. Meanwhile, the fugitive Grant Ward is spotted by Agent Antoine Triplett accessing one of his hot boxes, where he has money and supplies. Triplett lets him go when he realizes that Ward has rigged himself with an explosive in case S.H.I.E.L.D. attempts to take him. Evading Agent Bobbi Morse, Ward gets on a bus to Boston, though Agent Lance Hunter is already on board, ready to follow him.

In the memory machine, Coulson remembers the patients of the T.A.H.I.T.I. project, who all first appeared to be normal, before going crazy and obsessively drawing alien symbols everywhere. Coulson wanted to shut down the program and destroy the alien host immediately but was presented with a different option – erasing the patients' memories so that they would have no knowledge of what was done to them and could carry out normal lives. In the machine, Coulson struggles to remember the patients' names, eventually succeeding. Realizing that one of them, Sebastian Derik, has been targeting the other patients of the project, Coulson rushes to the only other survivor, Hank Thompson, hoping to get there first, locking Skye in a holding cell so that she cannot interfere with his desperate attempts to discover the truth. Coulson holds Thompson at gunpoint, attempting to learn all that Thompson knows about the symbols he has been drawing, but Thompson has not been drawing them and knows nothing. Derik knocks Coulson out from behind, binds and gags Thompson in his workshop, and ties up Coulson. Derik informs Coulson that pain drew out his suppressed memories, which is how he found all the other T.A.H.I.T.I. patients. Thompson escapes from his bindings, and some deep-rooted S.H.I.E.L.D. training helps him assist Coulson in breaking free as well. Thompson rushes his family to safety while Coulson struggles with Derik. Skye and Alphonso "Mack" Mackenzie arrive and threaten to shoot Coulson, who has Derik trapped by the neck. However, Coulson is not trying to kill Derik, rather he is trying to get him to look down at a large toy train track Thompson had constructed: it is a 3D model of the alien writing, which is actually the blueprints of a city. Thompson had created it in the image of the city without realizing.

Thompson turns down Coulson's offer to rejoin S.H.I.E.L.D. while Derik is turned over to authorities, having found his peace. Coulson has also found peace; as realizing the writing is in fact a 3D diagram has satisfied his compulsion to carve the symbols. In a bar in Boston, Ward meets Hydra agent Sunil Bakshi, and informs him that he wants to meet Whitehall. When Melinda May's S.H.I.E.L.D. team storms the bar, they find Ward gone and everyone dead, except Bakshi, who Ward left as a gift to Coulson. Coulson vows that they will find Ward eventually, and will take advantage of his gift. Coulson then briefs all personnel at the Playground about the city blueprints, explaining that he is not crazy and has been trying to solve a puzzle, just like Hydra. S.H.I.E.L.D.'s primary task now is to find the mystery city before anyone else.

In an end tag, Ward calls Skye and promises to keep sending "gifts" from time to time, before hanging up and preparing to deal with his brother, Senator Christian Ward.

In October 2014, Marvel announced that the seventh episode of the season would be titled "The Writing on the Wall", to be written by Craig Titley, with Vincent Misiano directing.^[1]

Asked if Coulson will be "back to normal" following this episode, star Clark Gregg said "He really felt like he was losing it in the first part of this episode. Since he was going around trying to figure out who was going to pull his plug, that's a real concern. I don't want to die again. I was so surprised when it got to that bit in the script at the table read. I was like, "Oh, am I better now?" And they went, "Well, let's just say you aren't crazily carving anymore."" On whether he will have the same drive to find the newly revealed city, Gregg said "One of the really cool sci-fi elements of this show is that whatever this is, it seems to have been around for a while, and once it gets into your system, it starts to influence your behavior. I've seen a couple of really creepy, scary nature specials lately about insects who do this, that infect another species of insect and get them to do their bidding, often in a suicidal way. There's something kind of sinister about it like that. I don't know that having solved the carving element of it or figuring out the city part of it is going to completely mean that that alien tissue is done with him."^[2]

Talking about the motivations of Ward in the episode, Gregg explained "Ward seems to think that he's redeemable, and yet for every step he takes that seems to be about mending fences with either Skye or Coulson, he seems to do something that's equally psychotic. The speech that was in last week's episode, the bit between the two of them before he turned Ward over, it seems like Coulson takes the deaths of Victoria Hand and others very seriously. I don't see how Ward is going to explain that away, from Coulson's point of view." Then asked if Coulson would kill Ward, Gregg stated "That question actually goes right to the heart of Coulson. Would he want to? I'm sure Coulson does, but I also feel like there's a cost to not being Hydra. To Coulson, there's a very clear line that you cross over when you indulge your more primitive retribution-based desires, that suddenly really starts to rupture the membrane between you and what you're fighting against."^[2]
