>>98051945Depends what era of their life this takes place in. Either it's during the main part of the series where Rigby's incredibly clingy and needs Mordecai by his side, the rough patch where they're not working together anymore and Mordecai's gotten fat/had a mid-life crisis, or when he's with his wife and Rigby visits sometimes.
In 1, he's always with him, in 2 he's more likely to stay around Eileen, in 3 Rigby might visit sometimes but won't affect the neighborhood that much.
