In season 1, her importance was to join and betray Heather's alliance. In season 2, she becomes a more important character. She first joins Justin's alliance only to betray him by voting him off in The Princess Pride. She then joins Courtney's alliance just to betray her by not respecting her wishes. In regard to character, she hasn't had any real development except concerning fear. Such examples of her bravery are conquering her fear of bugs in Phobia Factor, locating Geoff and Bridgette in Alien Resurreggtion, and going on Geoff's expedition in the TDA special. One of her problems is her wannabe attitude being portrayed in season 1, then barely at all in season 2. Her other fault is her duplicity, as revealed in the Aftermath IV. A clip of her was shown eating a basket of cookies in front of the girls' cabin, even though she'd say she'd never do that kind of thing to her friends.
Except for the last three sentences, I think this is generally a positive review. Although betraying people sounds harsh, it's her strategy. And in season 2, it pays off well.
