Matthew is a unseen character from the episode "Esteemsters." He is mentioned in passing as Quinn Morgendorffer takes his call, ostensibly for a date. The call seems to break her out of the depression she expresses to her parents after Daria had announced that they were sisters.

Quinn receives another phone call from the still unseen Matthew in The Lab Brat, juggling dating him at the same time as a Roderick.

In Fanfiction[edit]

Matthew appears as Quinn's love interest in Otherwise Known as Quinn the Great, a story by Austin Covello.
