Chapter 6 - Not a Chapter, but a question.

So I'm trying to write Mia's reaction to Brian being an undercover cop, after explaining to her how he grew up. I'm thinking she'd feel betrayed and confused and try to storm out, after giving something so precious to him...who was faking it... himself the entire time in her eyes. Or should she find it hot and a little confusing, but in the end flattering that Brian is about to throw away everything because he fell in love with her...?
