I think the reveal to Ahsako that Vader IS Anakin is something that could be explored. Granted, it's probably going to be sensed thru the force, not by Vader going soft on her crew or anything like that, but that first sense where she can tell.

I thought when Fitz saw what Simmons was doing, he immediately knew that she was purposefully researching the item incorrectly and that Simmons was going double agent, so that Fitz could leave comfortable in the knowledge that she hadn't turned to the other SHIELD. Hence the line "but why would she be looking at…?"…

I liked the episode. I especially liked the scene where Ginsberg spotted Lou and Cutler. He's trying to read their lips, and all you hear are electronics humming, ala 2001.
