Flash episode 22 Major Spoiler

[floramon]

The biggest plot hole i'm really seeing right now, is that there's no way the Savitar that Future Barry (2024) beats is the same one he's been fighting. If he's already broken out of the prison, and has the solution to not be locked away, then it stands to reason he can't be put there again. 

Please no more going back to the past and save Iris. Just let her RIP.

I don't think in the finale we'll see how Barry defeated Barrytar because:
1) within 45 minutes, he has to find Captain Cold. Who told Barry that Cold is not dead? And where to find him? And why him???
OK, 'Drama' - we won't see any explanations. Captain Cold will agree immediately.  :P

2) Cisco is still persuading Killer Frost. OK, 'Drama' - KF suddenly disappeared.  :P

3) they will surely take a long time to mourn for Iris and we'll see a lot of flashbacks.  :P

Squeeze everything into 45 minutes (find Cold, persuade KF, mourn for Iris, defeat Barrytar)  

In season 2 finale, Barry returned to the past to save his father.

I have a bad feeling that in season 3 finale, Barry will return to the past to save Iris.

And then in season 4 created another Flashpoint among Flashpoint. And then Reverse Flash also returned. See how complex it became?
