The actor then went on confirm that he's been reading up on the Reverse-Flash in case he ends up taking on that role somehow, and talks below about what he finds interesting about the Thawnes. He seemingly goes on to confirm that both Reverse-Flash and Wally West are indeed on the way, along with Cobalt Blue! "It was fascinating to me, and I think the family lineage -- they're quite wealthy and they're from this old money world of deep, deep dark secrets. It's also fascinating with the whole Barry's twin [storyline], and who that is and who it's going to become. You also not only have the Reverse-Flash, you also have the Wally [West] kid, and we've had Wentworth Miller on the show and all sorts of amazing guest stars like Robbie Amell already. Things are turning over quite quickly, and I think you're going to see some people in other suits pretty soon." Of course, Cosnett could be referring to what he found interesting in the comic book here, but the fact that he includes Wentworth Miller in the same sentence makes me think they're elements that the show will explore. For those of you who don't know, Cobalt Blue is Barry's twin brother who was stolen by an inept doctor responsible for killing one of the Thawne's children. As a result, he was brought up the this family and ended up becoming one of Barry Allen's main villains!
