yes! two possibilities, actually. his most recent ex girlfriend. they were living in new york together until she found out he was cheating on her during his work travels. he was since caught drinking on the job and fired so he's made his way back home to portland, where he's crashing with his parents. even if he did her wrong, she cared enough to follow him to portland to see to it that he picks himself back up.
the second option is his best friend! basically cradle to the grave. even though he's been away for the last 5 years or so, they've made visits, kept in touch, etc.
