I am having SO much fun with Brady, and I'm really glad people are getting so worked up over him. :D

Dean is NOT used to sharing his Sammy. It was one thing when Sam "walked out" on them, because then he didn't have to think of it as Sam being with other people. It was just Sam not being there. This? This is different. Jess is basically competition for Sam's attention and affection, even if Dean wants him to be happy.

I love Dean, but I don't think he's a saint, and he's only a martyr because he needs his family to an unhealthy degree.
