Mai is some emo/goth chick that served absolutely no purpose to the show. By the end of Season 2, Mike and Bryan finally realized how much of a waste of space Mai was, so in a an effort to make her less pointless to the show, they made her hook up with our favorite emo in Season 3. Eventually, he broke up with her to hook up with Katara help our lovable, but criminally insane hippie save the world! He got back together with Mai, when he found out that Katara wasn't emo, like he thought she was.
