Sure, Wally was able to reverse Zoom's attack on Linda and save their babies, but Keystone-Central got trashed, most of the Rogues/new Rogues were out of Iron Heights, two of the reformed Rogues did Face Heel Turns, and all of the supervillains heard what the superheroes had done and bunched up in VILLAINS UNITED as a form of protection against the mindwipe-ry.
Personally, Barry telling Hal that he'll find the Rogues' graveyard had me wincing. The Rogues have *killed* to recover their dead before. Why the hell does Barry think they're not going to go after him if he tries to dig up Avernus?
