Marissa Benson is Freddie's meddling mother. They live across the hall from Carly and Spencer Shay. Marissa is nosy busybody and frequently embarrasses Freddie in front of his friends, often by going too far to try to protect him. She usually means well, but is an ongoing source of annoyance and antagonism for Freddie. Marissa sometimes seems to dislike Carly, perhaps as an extension of her over-protection of Freddie.Background: It is unknown what happened to Freddie's father Leonard, but she has a fear that Freddie will leave her. She is a germaphobe who uses sanitizer to open her own front door and gives Freddie monthly tick baths. She is a skilled double sword fencer and comes from a long line of fencers, The Fencin' Bensons.
