But it might indeed be an Earth-1 Jesse that brings a completely different personality and attitude to the S.T.A.R. Labs squad.
We do know of one new-to-everyone character being cast for The Flash Season 3, and he sounds a lot like Barry in that he’s really smart and really nice and has some secrets that he doesn’t want anyone to find out.
But that doesn’t mean we can’t get at least ONE more, and possibly two if Wally West also starts showing signs of meta-maturity.
If it was up to Violett Beane, we’d be getting a version of Jesse Wells that takes little time developing heightened abilities.
