there was serious mess up in schedule inthe cw this year according to my sister, and it'll be a while ,but we will see barry make the trip to earth end up on super girls earth and still head there to earth 2 and back.
I don't think that's accurate. Maybe, but, we already saw Barry move away from the larger tachyeon device that he was wearing when he visited Kara, and he also seemed surprised to be "back" after he arrived at Star Labs, implying that he'd gone to her world and returned, so I don't see how that'll happen later (unless more time-travel). Seems more like it wasn't handled well.
let just wait it's possible Jay is ether made up alias like in small ville or the man inthe iron mask is the real one .
Well, if it's an alias than we have to wonder how mental-patient HZ came to be a passable scientist in such a short amount of time (good enough to fool actual scientists), and if there's a third one than yeesh, this narrative is getting sloppy.
cause that's not how villains think. he did kill his version of cisco and he was there waiting for weeks after that stupid mistake.
So is there a wiki entry on how villains think? 
Only teasing. I appreciate you trying! Not much of an answer, though.
technically he convinced an ehco(it's an entity spawned from the time stream ) not his actual past self. if it was his true past self he shouldn't exist ether after his past self death.
An echo that is... sentient? That can make decisions and choose to perform an action? How is that any different from a past version of HZ? I get that a speed mirage is a projection, but if HZ convinced an "echo" to do something, then that echo can't just be a projection, it has to have awareness, making it a real entity, which... how would that differ from past HZ?
yeah well your head will hurt more so I'll have to be careful with the explanations
