if you'd like him to have a roommate he could be newly roommates with harley! i was having harley move back into his old apartment that he'd recently moved out of, and i'd always had the idea that it had two bedrooms and everything despite him living alone? only if aaron loves cats though because harley has a very cute overgrown kitten with him. that would definitely work for me! harley tends to be really, overly affectionate with people unless it's in a work setting so if they met through there initially it would've helped temper that aspect about harley for sure.
