INTERESTING. So I don’t think he’s met the Avengers, aside from Steve and Natasha (obviously).
And he’s very… He’s trying to keep his distance from Steve, because Ren knows he’s in the wrong and that the Winter Soldier tried, on several occasions, to kill Captain America on the basis of false information. Ren’s also aware that Steve has infinite amounts of knowledge on their friendship and their past together, and this also unsettles the Soldier quite a bit because he remembers nothing of it.
As for Natasha, he only knows her as the woman who worked with Captain America in bringing him down, so he’s wary and suspicious of her. Again, Natasha has more information about their relationship and past affairs than he ever will, which is disconcerting for him.
So avoidance and distance is key here. It makes Ren feel better because it’s easier than facing up to the truth and the problems he’s caused.
And then the others he’s fairly indifferent to. Generally speaking, Ren thinks Stark is a “pompous asshole” and the Hulk is a “bigger problem than I am”. But it varies based on who i’ve interacted with. I think his friendship with gildrmunr is interesting and also think he’d get along with ofalloys and mechanicstark quite well once he gets over the pompous assholery.
