Spoilers for The Flash Season 2 finale follow.
With the recent news that Supergirl will be flying from CBS next season to join her superhero cousins at The CW, fans are excited at the prospect of Kara Danvers and company lining up more closely with the worlds of The Flash, Arrow and Legends of Tomorrow. But there’s one big question in particular surrounding this move, and it has to do with the fact that, technically speaking, Kara doesn’t even live in the same world as Barry Allen and Oliver Queen.
Of course, that’s not necessarily a big deal in the Arrowverse, where the Flash proved this past season that visiting alternate Earths is easy enough. In fact, he even met up with Supergirl when he used the Speed Force to jump across an even greater obstacle than the dimensional barrier — yep, the Flash managed to cross networks and show up on CBS.
