Well, we finally get the answer we have all been waiting for since the start of the season and it's a doozy. It turns out that the reason Jemma Simmons left SHIELD and Fitz is that she is now working as a mole in Hydra. If they can't defeat them from the outside, why not try from the inside. I think their intention is noble and that they think this is a good idea that is going to work. But this is how I see it playing out. Eventually Simmons will in fact be turned and become a real soldier for Hydra and the one person that will be able to bring her back to the good side will of course be Fitz. It HAS to be him and I think in the process of bringing her back, it will in essence save himself.....bringing back the part of him that is now missing. I really liked the scene where Fitz confronts Ward for the first time since he tried to "kill" him and Simmons. Very powerful moment for everyone involved.
