I mean, if Peter is also staying at the Invincible, then they at least exchanged pleasantries.
Jason literally went around during his first week and tried to say hi to people |D He was a camp leader for a long time and this felt a lot like camp. Gotta meet the neighbors!

Jason has a pretty decent track record with Marvel characters. The last game I had him in he developed a pretty awesome friendship with a comic book version of Scott Summers. He fits in pretty well with the hero types for some reason I cannot possibly imagine...
