Wally is obviously a smart person, but I don't think he has the ability to replicate an accident that one was random chance and would involve lightning, particle accelerator, and all those chemicals. Also he didn't witness this accident so I don't think he could replicate it. Maybe the energy did leave Central as well. That would explain Deathbolt being in Opal and would make sense for Wally.

ReverseZoom101 I agree with the spilling into Keystone theory. I mean like I said Wally is a very very smart person (we saw that when he was working on the grease car), but I just don't think he would be able to replicate an incident which he didn't even witness or have really any info about.
