Yes!!! Sig isn’t into actually racing (unless it’s hover bikes) but he’d definitely take in a race and bet. Maybe that’s how he came to see Ames? Like he vaguely remembered his really bad crash and his leg having to lost, which would have been pre-his own cybernetic surgery and then when they reunite on terminus it’s like oh damn! We both got cybernetics! Of course if Ames isn’t comfortable telling him about the ordeal that’s fine too, he might’ve just remembered reading about it on a newsfeed but he’d try not to bring it up! It’s also perfect because I’ve been wanting someone familiar from nibiru.
