Marvin 'Mouth' McFadden first appeared on the screens of 'One Tree Hill' during the pilot, as a High School Junior. He transferred to school in Tree Hill when he was young and has been a friend of Lucas Scott since they were in elementary school. He is often seen as a 'geek' or 'outsider' by his high school peers, but is generally a very well-liked person due to his loyalty, caring nature and non-judgmental attitude.Although he was not an athlete himself, he has a passion for sports. Lucas saw this, and Mouth would be included in the group of guys who would play basketball at the river court, with Mouth and his best friend, Jimmy Edwards being their sports announcers. When Lucas joins the Ravens, Mouth and Jimmy start 'ravenshoops.com' providing commentary on all the Ravens basketball games, as well as interviews with the players and their coach, Whitey Durham.He has had a long time crush on Brooke Davis - captain of the Cheerleading Squad. He was upset when he realised that Brooke saw him more like a little brother than a potential boyfriend. This frustration came to a head when she started a 'friends with benefits' relationship with new boy, Felix. A chain of events lead Mouth to get drunk and vent his frustration by putting a brick through Brooke's car windshield. She believes the vandal to be Felix, but Mouth eventually owns up and apologies, declaring his true feelings for her and why he did it.Brooke first thinks that they can no longer be friends, but their friendship is mended when Mouth comes forward to be a peer advocate for Brooke when she runs for Student Council President.Near the end of their Junior year Mouth starts a relationship with Brooke's competitor, Erica Marsh. Over the summer vacation Erica dumps him because she becomes 'too popular'.During their Senior Year, Mouth becomes the official commentator for the Ravens games, and is joined by Gigi Silveri, a sophomore student.He strikes up a friendship with new girl, Rachel Gattina. He develops a crush on Rachel, who leads him on a lot. Brooke and Mouth fall out as Brooke believes Rachel is using Mouth to get back at her. They fall out when Rachel confesses to Mouth that she was the one who released the Time Capsule and posted it on the internet. Eventually Mouth forgives her, and continues to keep the secret.Mouth gets a job at a local news station only at the mail room but his knowledge of sports got him offers from a station in Omaha where he briefly took it but before he left he fell in love with Brooke's assistant Millicent Huxtible and soon comes back to Tree Hill so him and Milli can move in together.
