Napoleon Dynamite

Can anyone tell me who is the girl on the bike at the end that rides up to Uncle Rico?? It's driving me crazy i have watched the movie so many times to see if i missed a reference to her in the movie but i guess i keep missing it. Help please it's driving me crazy!! By the way Napoleon Dynamite is one of the greatest all time movies

I always thought it was his girlfriend, the one that left him because he was living to much in 1982, but i could be wrong.

yeah i thought it was his wife or something

no, its his old girlfriend
