Something about the entire undercover scenario felt a little forced. And a little repetitive. Also, the entire "this week, the team is in danger" situation with the Bus didn't seem to have any real stakes or urgency to me. They pretty much telegraphed the fact that Fitz would come up with the save. Though, I did enjoy the actor's (can never spell his name right) performance and the bonding scenes with Mack, Hunter and 'em.
The May vs. May fight was really well done. The director (Mo Tancharoen's brother) has some experience with heavy action choreography with the Mortal Kombat web-series and it showed. Whitehall was menacing, and I'm starting to enjoy his #2, Sunil Bakshi as well... not sure if I can completely buy him as an Indian guy, but that's about as minor as a qualm gets.
Overall, solid episode, but a little weaker than the first three episodes of the season. Can't wait for Mockingbird.
