So how did Jenna end up being a '6th chick'.
I get she wished to be 30 and all.
But how did she suddenly go from a geek who was tricked and being taken advantage of by being forced into doing their homework into a cool 6th chick who went to a dance with her hot crush.
Something doesn't add up, they obviously never liked her! Or else they wouldn't have left her party while she was in the closet or tricked her into doing their homework.
