I think the thread title can now be changed to "Harrison Wells IS the Reverse Flash".
That was my prediction when I started this thread and I think that it's
pretty much established that he's RF.
As Cain suggested in an earlier post Wells/RF travelled back in time, killed Nora Allen, (which means that Barry will end up travelling back in time to stop him, and end up saving himself, the old "predestination paradox" but also ensures that Wells/RF exists in the future. So then Barry returns to the present, whereas Wells/RF loses his powers and has to get back to the present the same way the rest of us time travel, at 60 seconds per minute.
Anyway, when Barry gets his powers, WElls/RF gets his back.
Why the tachyon device ? Obviously for time travel of some sort, but backwards or forwards ? Maybe he's looking for a way to escape the time paradox ? Who knows, but I can't wait to find out !
As far as being in 2 places at once. Wells set up that whole scenario, so he could have worked something out in advance - holograms could be involved, and of course RF certainly has the speed and control of his powers to appear to be in two places at once - or it could be that there are actually 2 of him (1 that's travelled back from a different time and current Wells).
Someone pointed out that Harrison Wells ( H. Wells) all you need is the G and it's a pretty obvious pseudonym. I'm thinking that Wells is Eobard Thawne (which is why he won't kill Eddie, who's probably an ancestor)
Also, the whole manipulation looking-like-he's-helping-when-he's-pulling-the-string-from-behind-the-scenes thing is a pretty standard MO for the ol' RF.
(finally bought the collected "Return of Barry Allen" graphic novel, man what a great Flash story ! What I've always liked about the Flash is that despite all the **** that he goes through - and he goes through a lot - he never goes the old "Dark Avenger" path and remains one of the most lighthearted and upbeat of superheroes. If you haven't read it, and like the Flash, it's worth a read - although of course it's Wally West, who IMO was a great Flash ).
