TMI - Sometimes he secretly steals and uses Guest's toothbrush. - When Guest isn't home, he buries his face in Guest's clothes and pillows to sniff them. - He has kissed photos of Guest many times. - Deep in his drawer, there is a collection of Guest's hair ties, combs, clothes, and... other items.
