oh i think these two are going to be two of a kind. in his own way robb can be very charming, he's very extroverted and active, socially engaging and friendly so long as he's content and sees the possibility of gaining something but he has a tendency to wreck things and people just for the joy of wrecking them and the power trip it gives. that probably conflicts with finn sometimes trying to not be trash, so maybe that's why they still have that 'enemy' part of frenemies going?
