I doubt this episode would've been filmed within the last two and a half weeks.
I know I defended her in the past, but I'm starting to have a hard time accepting the direction they're taking Gemma. I know a lot has happened to her, but for her to go from the mousy lab geek she was last season to someone with a murderous vendetta is starting to seem like a stretch. Though, I think Fitz not even really raising an eyebrow at her suggestion that they murder Grant in cold blood strains credulity a lot more. I always saw him as being the moral fiber of the team. He was the only one to stand by Skye when she was in quarantine, and he remained loyal to Coulson and was willing to resign from SHIELD to get him back the toolbox. I would think he'd have at least raise a little bit of an objection to Gemma doing something that could put herself in danger, not to mention jeopardize the mission and undermine Coulson's plans.
