We've only seen Senna in three scenes, one in which she was teasingly flirty (and given what Gary interrupted, that's as good a reaction as you can hope for), one where she recruited Sandra and one when she as at work. It might be a bit early to call her a lost cause just yet, 's all I'm sayin'.

Personally, I've no real problem with her. She's doing the model diva thing, exaggerated a bit, sure, but it's comedy. A friend of mine who's worked in the movie business tells me that the latest scene isn't that far from the truth.
