Dabi and Kurogiri is deeply weird, but kind of interesting. They're very different, especially emotionally speaking, so maybe Kurogiri's nurturing and patience would be grounding?
This is so funny to me because I don't actually have an interest but I do feel like Roland and Makima could have this Gone Girl relationship (where he has been working at her side for years then she suddenly reveals lots of bad) that would be totally insane
