I admit it, I was worried when I saw this, so I googled and I watched the promo.
Know what I think?
Future you thinks that Hydra has the key to helping Fitz. And that's why you're there. Maybe Coulson knows, maybe he doesn't, maybe you've done this on your own, but I don't believe for a second you are actually a Hydra agent.
Hell, maybe I'm wrong, maybe you've been playing everyone and you're playing us all right now. But I don't think I am. And I tend to know people quite well.
