"I think there's an unfortunate off-screen sound effect that might have given the idea that, "Oh, he clumsily did something," rather than the fact that it happened," Bell told Paste. "I don't know that he knows or feels responsible, but he absolutely knows she's gone. They would have had surveillance footage of the room, and, knowing Fitz, I would expect he's doing nothing less than putting all of his resources into trying to get her -whatever that means."

Unfortunately, by time the premiere roles around, Fitz will be the only member of SHIELD still on the case. After several months without a lead, most of Coulson's (Clark Gregg) team will have written the scientist off as dead.
