Ares getting to flex just how badass he is is always nice. And its not just that he's powerful but also extremely logical which is a great boon in battle, taking advantage of the vampire's cockiness and ego despite the fuckup from the Hero. I kinda hope he just goes keep on doing vigilante shit and doesn't bother with them.
Speaking of the Hero, we finally got confirmation that she's a girl and the reason she kicked him out was because she needed to hide her status as a girl...despite the fact that Ares probably would not give a single shit, not that she'd know it. At least she seems a bit remorseful about kicking him out without giving him a suitable reason so for now she's still just a naive dummy to me and nothing worse. She does need to buckle down and start listening to others more if she wants to be an actual successful hero though.
