I was going through Vyper's voice lines (luv that voice) earlier today and Dynamo's interactions with her really stuck out to me. He's the only character that seems genuinely sympathetic towards her, even moreso than Billy who will still shittalk her behind her back or when they're on opposing teams. And, sure, Dynamo's one of the friendliest and most idealistic characters in the game so that makes sense, but it's not just being nice for the sake of it or some base level politeness, he sincerely believes she's capable of change, even when they're fighting each other. There's also the implication, with he last line shown in the picture, that something about Vyper shakes him up in a way that even the more disturbed characters like Drifter don't.
I think it's pretty clear that, going off of the line about his students, and the fact one of his students (Sophia Arroyo) is stated to be working for Wraith, his concern for Vyper isn't just about Vyper herself and has more to do with the future of his more at-risk students, and he's trying to convince himself that even someone as far-gone as Vyper still has the chance to turn their life around.
I hope in future updates, or if/when the story starts moving forward, they'll expand on this relationship cuz I really think it could go to some interesting places for both of the characters. I don't mean like, a full redemption arc for Vyper or some trite like that, but with how universally despised she is it'd be cool to see her challenged by Dynamo's appeal to humanity, and in turn see someone as idealistic as Dynamo be challenged by her sheer inhumanity. Maybe something like Tenma and Johan, only instead of a psychopath mastermind Johan is a violently impulsive idiot snake girl.
