Overall this Season of the Flash was enjoyable though some of the temporal illogic made my head hurt at times.
If Savitar's existence is indeed erased, then shouldn't his actions have never happened? Guess not as sometimes time still happens, regardless.
The Speed Force exists outside of time, so the Speed Force cage would still exist with in it. Though WHY the SF doesn't somehow destroy the cage now that Savitar is erased is a good question.
Nothing against Gustin, but I hope that Barry is gone for most of the season. I'd like for Wally to grow a bit as Kid Flash, also Jay can visit from Earth 3 from time to time and Jesse can return to be with Wally and work with him to keep Central City safe.
Wells 2 will be there as well and I suspect he and Cisco will be devoting much of their time to getting Barry out of the Speed Force, when they aren't fighting metas.
Also I am hoping that Cisco starts upping his game both as Vibe and with Gypsy.
Let Barry stay in the Speed Force for awhile, maybe show him viewing what is going on in our world and getting restless even as he learns new things about the Speed Force and his powers.
Also I can think of ONE way to get Barry back and to also hopefully prevent the creation of Savitar,....in a desperate move, Wally or Jesse hit time warp speed and go back to BEFORE Barry went back to create Flashpoint and tell him to not do it, thus the Flashpoint timeline we had in Season 3 undergoes a major revision.
Frankly, I really can't see Wally being a front guy. He's already the least interesting character of the series. I predict Barry will be back soon enough.
