Great film - but I don't get the Baja character

Watched this film a number of times now and really like it. Certainly makes you train harder if watched while working out! Has a little bit of everything and is surprisingly well acted.

The only thing I've never really got is the Baja character. Her sudden change from flirty, seductive, care-free girl to the introspective girl who shows all her insecurities to Jake (ie the scene where she apologises) just doesn't sit right with me.

A few questions I'd asked:

How on earth would she be with Ryan in the first place if she feels this way about fighting? Would be interesting to see a couple more scenes of her and Ryan together becuase I can't imagine how they'd even talk to each other about anything they have so little in common. Also, surely she knew that Ryan was planning to beat Jake up when she invited him to the party. The first time she saw Jake you could see that she liked him and thought he was different/interesting etc so I don't understand why she would basically plot to get him beat up. Which is what she did in my eyes becasue she knew what Ryan was planning deep down.

Interesting but flawed character. I wish she had been developed more in the script and, like I say, there had a been a few more scenes showing her and Ryan togther.
