yes! so i did talk to bear and matt did get babysat by squirrel girl, so they are 'friends.' matt has a lot of conflicting traits but the arrogance and the non-seriousness are probably the most noticeable/dominant when he is hanging out with people. the annoying douchebag competitive part is less prominent.
he probably thinks kassi is hot and has hit on her, thinks cal is awesome, gabe is weird, and billy is also weird but cool.
