Barry was beating the crap out of Barry. That was the only way to explain what was going on. At least a dozen Barry Allen were fighting each other in a confused, frustrated battle royale involving all abilities, and  weapons. There was no way to figure out just by watching who started it but someone who wasn't Barry Allen had to finish it.

It was a mess right now with Barry hitting himself again and again with damage all over.
