Jamie has blonde hair slicked back with an undercut. He wears a black T-shirt, grey pants and an unbuttoned green button up. He is known for having a very deep voice. One of the "Triple J's" that follows Quinn around. He hangs out with Jeffy and Joey.
He stands apart from the other Three Js is the following ways:
Quinn repeatedly forgets his name, calling him either Jeremy, Jimmy, Jamiel or Jerome. Daria has also been shown to forget his name and several teachers. Enough people forget it that in Fair Enough, he sounded ecstatic that DeMartino had got his name right.
Despite the name-forgetting (or perhaps due to it), Jamie is the only one of the Three Js to have been given the last name, 'White' (revealed in Fair Enough).
In "Write Where It Hurts," a passing comment reveals he is married to Quinn in Daria's story about the future. Since another episode reveals that Daria can't keep track of which of the Three Js is which, she may have just chosen his name at random.
If his parents die, he will be taken in by "this creepy old aunt." According to Jamie, "she smells." (Groped by an Angel)
Quinn is Joey's ultimate crush; he and the Three J's follow her around like sheep. He is willing to do practically anything for Quinn. Quinn, briefly, "goes steady" with Jamie in One J at a Time. He was the first of the J's she chose in the episode, and she selected him via "eenie, meeny, miney, moe." He is aghast when the other J's abandon him as a result. (The relationship lasted a single day, doomed after he had to pee during an hours-long monologue from Quinn about make-up)
The three boys are known as the Three J's. All the boys are on the football team, and they all fight for Quinn's love as well as tease each other near constantly.
