Honestly, Drift's pretty used to being treated with suspicion and contempt by other Autobots, but the suddenly accusatory tone and the comment about Overlord in particular really throw Drift, and he reels back with a stunned look on his face. When had this mech joined the crew? He must have been present for the catastrophe with Overlord, to look at him like that, to say it with such resentment. His optics are wide and shocked for a moment, but then he holds his hands up, looking defensive.

"Other people have filled me in, but I don't remember those things myself -- I told you, people arrived here from all different points in time." He still looks stunned, stricken, maybe even a little wounded at the sudden turn of conversation, but then his optics sharpen. Delphi and Overlord he knows about, but...

"Wait -- what happened at Crystal City?"
