Charlie: Why, so you can get shot again?
Don: No, buddy. Look, I understand, I appreciate you care about me, but it’s not gonna happen.
Charlie: Statistically, you’re dead now. You understand what that means? A man aimed a gun at your head and fired. The fact that you survived is an anomaly, and it’s unlikely to be the outcome of a 2nd such encounter.
Don: I’m sorry. I’m sorry. I need your help, you understand?
Charlie: I don’t think I… that I can…
Don: Charlie, I know it’s hard for you, I understand that. But it’s hard for everybody! You know, I don’t know how I got in a situation where I need your help to do my job, but I sure as hell have. And I wish you would just snap out of your precious bubble for once!
Alan: And your brother sure doesn’t understand why you spent the last 3 months of your mother’s life working on a Math problem.
Charlie: These guys know you’ve studied them. They know you’re trying to out-think them.
Don: Charlie, it’s all right. Me and Heisenberg, we’re all over this.
Don: How you doing on your “P vs. P” thing?
Charlie: I’m not pursuing it anymore.
Charlie: I got plenty of problems to work on, ones that I think I can actually solve.
Don: Glad to hear it.
Charlie wasn’t ready for the possibility of loosing Don. He freezes again. Don doesn’t fully understand, not before (when their mother died) and not now; he needs his brother help, but he also wants to protect Charlie. Their father, again, makes the bridge between these two different worlds and point of views. It’s all about love and lost… Love them!
