Whilst Arrow, The Flash and now Legends of Tomorrow all largely operate on their own as shows, the characters in these shows arent afraid to lean on one another if the need arises. As such, Oliver Queen has been known to turn up in Central City, Barry Allen may pay a visit to the Arrowcave, etc. With Supergirl now set to potentially exist in the same world as the Emerald Archer, Scarlet Speedster et al, these heroes have a new ally to call on should a dangerous, game-changing threat rear its head. In fact, whos to say that the Maid of Might couldnt turn up to help tackle the ominous presence of Damien Darhk or Zoom. Obviously large parts of Arrows fourth season and The Flashs second season have already been filmed, but theres no reason why the Girl of Steel couldnt be called upon at a later date. So, what are you expecting from The Flash's Supergirl appearance? Let us know in the comments section below.
