Yeah, I always feel like there is something bothering me in these timeline issues, but I prefer waiting until the end to know how they deal with it. But the question of Deke is interesting. Simmons takes his existence that she and Fitz survive long enough in the timeline, but this is a timeline they are trying to change...

I also picture Deke dying in the end, but not especially to return things to normal, more to help to save Fitz from his dark self.
