Headline: "Supergirl EP Reveals James' Future as DC Comics' Guardian, Explains Why He and Kara Are 'Best as Friends'"
As for why Kara ended things with James at the end of Monday’s season premiere, Kreisberg explained that the writers wanted to tell a relatable story, one in which a friendship becomes something more — even if it shouldn’t.
“We sort of felt like we were pursuing that relationship more because we felt like we had to than any of us was really truly feeling it,” he told reporters. “We realized the best scenes between them were the nice, sweet scenes where they were being friends.”
Half the reason I wasn't real invested in getting to season 2 was that I just assumed I'd have to deal with them being in a relationship for a while, but APPARENTLY NOT. Apparently this is as failtastic as every other romantic relationship they've started & ditched in the space of one episode. I'm fairly certain that's actually a terrible choice from a writing standpoint and probably does some character disservice to boot, but right now...
