Absolution - S3-E21
Continuity mistake: Fitz drags another agent through the door as it's closing, and one of the Primitives is shown grabbing at the agent's foot, barely missing before it goes through the threshold. Then, in the next shot, suddenly the Primitive is still falling through the air, trying to reach out for the foot that's already inside the door. (00:38:08)
Absolution - S3-E21
Continuity mistake: In the hangar, Simmons unlocks the security door so Fitz can escape the primitives. The control panel changes from a red SHIELD logo reading "RESTRICTED AREA" to blue reading "CLEARED," indicating the door is open. However, moments later while Fitz is fighting the primitives with a fire extinguisher, the door remains open even though the panel shows red and "RESTRICTED" again, then briefly turns blue before switching back to red as it closes.

Absolution - S3-E21
Continuity mistake: On the security camera, Fitz yells at Simmons that she has a good memory, then asks, "I mean you do, right?" and then he starts to turn to look at the Primatives advancing on him. He's standing up straight, back against the wall with both arms down at his side. Then it jump cuts to a front view of him, and suddenly he's bent over with one hand planted back against the wall.

Chosen answer: Coulson believes he was resuscitated then sent to Tahiti to recuperate. "A magical place," he calls it. But in the "Agents of S.H.I.E.L.D." episode "The Magical Place", Coulson, through a mind-reading machine, learns that he was treated by S.H.I.E.L.D. and a fake memory of Tahiti was placed as a "mask" of sorts over the painful memory of the operation, which involved a drug seemingly of alien origin to repair the damage, coupled with a lot of morally dubious surgery.
