The two won’t have a ton of time to relax though, as The Flash Season 4 is introducing one of the hero’s greatest adversaries, The Thinker.
While the villain will probably be one of the toughest our hero has ever faced, Barry got a little hint from Savitar last season on a way to fight him, so that tip will likely make things a bit easier on the team at some point.
(Usually due to something Barry did.)
No doubt Barry letting go of his past will also aid the hero in his fight, or it’ll at least prevent Barry from being such a sad sack back at S.T.A.R. Labs every time something goes wrong.
