Hey, I was just wondering why Supergirl villains do not count as Arrowverse villains. Although Supergirl happens on Earth-38 and Arrow/Flash/Legends on Earth-1, they are still in the same multiverse. After all, villains from other earths in The Flash count as well. And, although the Supergirl/Flash crossover episodes count, shouldn't all villains from Supergirl count, given that the crossovers show that the different shows exist in the same universe (especially since Supergirl is now part of CW as well)? What makes you say that " currently and canonically  Supergirl  is  still NOT  in the  Arrowverse ."?
