I love Mack, I adore his friendship with Fitz most especially, but I was really annoyed by how no characters seemed to care about Deke being stuck in the 80's. It was all, "Mack's alive..." and "We'll bring him back, he'll be okay" and not one word about bringing Deke back too. Even when they showed up in the base, obviously Yo-Yo would hug Mack, but not one person asked Deke if he was okay too. The closest we got was May saying hi to him and Coulson, but even she didn't ask him how he was after almost 2 years being away. I was like, come on... I know he's supposed to be the comic relief punching bag of the team, but what makes the show is that the characters are still human and have emotions and deep down they give a shit about one another and we get to see that. So to not see anyone give a shit about Deke really bugged me.
Also, when the F*** are we going to see Fitz again??? (I know the actor was off making a movie, but come on! This has to be a shortened final season, right? So, what, is he going to show up for one freaking episode and that's it? Unacceptable!) I really do miss him. Also, it makes me wonder, if Jemma was altered in order to do what she has to do, then what did they have to alter in Fitz?
