So Kara mentions that her cousin is frenemies with Bruce Wayne. Presumably this is a Bruce on Earth 38, which either is frenemies with him as Clark Kent, or frenemies with him as Superman. Either way, a really odd thing for her to say to Kate Kane out of nowhere.

There has also been an unknown vigilante previously mentioned that resides on Earth 38, and described by Winn as a frenemy of Superman. Kara also seemed rather suspicious of Wayne/Batman coincidences on Earth 1.

Really annoying there wasn't just a little bit more exposition in order to be able to properly connect the dots. I guess there now has to be a Bruce Wayne (Earth Thirty-Eight), which like the Earth 1 counterpart can't actually be connected to the vigilante?
