However, the truth of the matter is that the relationship between Enid and RA cannot last. There is an episode of OK KO that makes it very clear that she will eventually have to go back to her timeline to save her world. Enid and RA will not grow old or get married, that's a fact. And the last episode showed that Enid and Rad stuck around until they got old as fuck.
But even if she doesn't end up with Rad, she's not going to be with Red Action for a long time either. Their days together are numbered.
