I'm trying to figure out what "continuum" Supergirl all happens in?
Is this series set in the same world as Arrow and Flash? How about in regards the last Superman movie? They don't use his name, is that a license issue of some sort, and will that keep all these in separate worlds? Is the superman cousin here the same superman as in the 2006 movie?
In the marvels TV series, a non-comic book person like myself can be pretty sure it's all one world, and is consistent with the box office movies (Except for those embarassing early hulks they couldn't seem to get right.) It just seems DC is having trouble here.
