I'm a bit disappointed Barry's not actually dead. The ending of the episode, knowing that he couldn't die, failed to impress me. So I rewatched it trying to convince myself he had actually been decimated. Wow. That was good, and I mean really good, as if it was the intended interpretation. And would have been one major twist. We have two Flashes to replace him, after all, and capitulating to Zoom was a firing offence. And even though I like this Wells, I sometimes wish he got stripped out of his arrogance for good.
I'm unsure whether I would like whatever gimmick is going to explain his absence (“trapped in the speedforce” sounds intriguing when you don't think about it), but from the screencaps from the next episode it seems it will be put to very good use. That will be either very very good, or very very bad, but either way I'm thrilled.
It wouldn't be much of a show without Barry Allen. Even if Wally West were to take on the mantle, he's a secondary character at this point and hasn't been established and fleshed out.
