It’s not a sure thing that Supergirl will turn out this way, of course. Kara and the Super Friends still will have to fight Nyxly for the other totems in the coming episodes, so it’s possible there will be many more battles to come before the series finale. And who knows, perhaps the Supergirl writing team found a way to make Kara’s emotional link with Nyxly riveting, and we’ll get some real insight about both characters in these final episodes. Or it could be Supergirl’s version of Barry’s fight with the Speed Force in The Flash, which ended with characters living in a dimension with the Speed Force, so she wasn’t lonely. Trust me, Supergirl fans don’t want an equivalent of that storyline.
