I loved that costume! I want to see it replace the one we have now in the near future. Also thought they did a good job of making Barry look older.
As far as the Savitar reveal in light of Killer Frost's reaction, the thing that would make the most sense is Ronnie if, in fact, she was sincere about joining him. Maybe she is so terrified of who he is that she feels she has to do what he says or else she's dead?
Even if this doesn't turn out to be true, it'd be cool to see that version of Barry in some capacity and have him meet our Barry.
You know what we need? A straight-up Flash/Legends of Tomorrow crossover. Flash crosses over with Arrow and Supergirl so often, but we could learn a lot about time travel and how it works on both shows (and to solve the problem of Barry's recklessness) if they do a crossover just contained in two parts with only those shows.
Any way to work the Reverse Flash from Batman the Brave and the Bold into that theory?
Isn't it kind of implied that Barry is changing the timeline since Future Barry had no recollection of traveling to the future before Iris' death?
