How much love did she really have for Michael in the first place?
She might be a little hurt, but she can be rather good at figuring things out for herself (I really loved Angie's inquisitiveness, and her relentlessness when problem-solving. She figured out the bathroom door without anyone telling her, and while her hot-water distribution modification was pretty dodgy, it was better than Michael's.) I am pretty sure she had an idea that he was not completely on her side all the time. She might be surprised to discover that he never nommed her, that the three points she sent his way (preferring him over Estelle, too) should really have gone to Josh.
Layla's defection might surprise her, especially that she had sent a point Angie's way before the hickey on the neck fight. But even then, Angie suspected Layla was being got at by other people - that claiming that Angie was influencing what she thought too much was their way of influencing Layla. I am sure she has enough compassion and good nature to value Layla as a friend rather than a rival. And good sense. I can see Angie doing something amazing with her insatiable curiosity and agile brain, in the next twenty years. ( Michael's IQ seems to be almost a disability, an excuse for not even attempting anything that might be worth while. I guess if he wins the Vogel prize next year, I'll be the first to say I told you so, but really, he seems bent on dissipation, and embarrassing his dad, and feeling guilty for it, and channeling the guilt into still more mirthless frivolity. )
Not winning Big Brother might be the making of Angie.
