ii am very familiar with both actually!

and i definitely agree that adam and tim would probably get along betterish at first because they're close enough in mannerisms to bond well, but tommy is a chaos gremlin that would eventually grow on him. and adam would, begrudgingly, have to learn to accept that they're pals.

so i don't have a preference, esp since i know that adam will at some point get shoved at the rest of the yas and eventually meet tommy, even if he isn't the first one he meets!
