His story is hard to be believed after his intentional and knowing use of the Stoneskin potion and life raft capsule. Speaking of which I hope he didn't leave that extremely advanced capsule tech behind. Hard enough just saying yeah I suddenly have powers and ran with it. Its another to have a magic potion on hand and knowingly use it so assuredly.
So this leaves the question if its an alternate reality to the one he originally went to. Or if the hit on his parents succeeded later on and he still lost them. Also the question of not remembering Allen from being a kid. A traumatic moment that should've stayed even with his parents surviving and Allen looks very distinctive. Which reminds me. Felicia should be a Blonde right?
