Quentin was one of Joe Swanson's new friends in "Believe It or Not, Joe's Walking on Air", along with Parker and Portland. He is Glenn Quagmire's replacement and counterpart, after Quagmire was deemed too much of a weakling to be his friend now that Swanson had working legs again. Quentin enjoys exercising and the Dave Matthews Band. It is assumed Quentin and Joe broke off their friendship after Joe became paralyzed again. Quentin's name of course, starts with "Qu" as well.
