I loved Fitz/Mack and their banter.
The Robbie and Daisy scenes were pretty interesting too.
Robbie saving Fitz was great.
The scene with Fitz, Mack, and Daisy is my favorite scene of the season so far. They all love Daisy so much, and everyone is in pain and angry and they understand one another but it still hurts. I watch the show for the character relationships, and this scene had so many complex ones, whether ships or friendships - Daisy-Mack, Mack-Fitz, Daisy-Fitz, Mack-YoYo, Daisy-YoYo.
I want May to be okay.
I loved "I can do May." I think that trainee totally has a crush on May :) fun times.
Coulson/May's relationship was good here too.
I'm guessing Coulson's recommendation of a powered person people can trust was Coulson imagining that Steve Rogers would lead SHIELD and Coulson would totally get to work with Captain America on a daily basis, but then Steve left everything behind for Bucky and now Coulson's stuck with an impervious bureaucrat. :(
Overall though the new boss plot is not enjoyable for me so far. And the not-ghosts or whatever seem like a terrible plot, so I hope it ends soon. I like that it will bring Robbie into the main plotlines, but i couldn't care less about the characters who are in ghost form and all their internal drama, and I'm finding the thing May is infected with creepy but not actually suspenseful or intriguing.
