David Sheff : My son is out there somewhere, and I don't know what he's doing! I don't know how to help him! Karen Barbour : You can't!

David Sheff : So how you doing? Nic Sheff : I'm doing great, you know, just, um... um... just doing what needs to be done, and... David Sheff : What does that mean? Nic Sheff : I'm sorry, Dad, um... David Sheff : Why don't we just have lunch and talk? We can do that, right? Please. You think that you have this under control. Nic Sheff : I understand why I do things. It doesn't make me any different. I'm attracted to craziness, and you're just embarrassed 'cause I was like... you know, I was like this amazing thing, like your special creation or something, and you don't like who I am now! David Sheff : Yeah? Who are you, Nic? Nic Sheff : This is me, Dad! Here, this is who I am! David Sheff : This is not you! This is not you, Nic! Nic Sheff : What are you doing, huh? You always gotta be controlling everything all the time! David Sheff : Let me book you a room at a hotel for a couple nights. Nic Sheff : No, Dad. No, Dad, I want it to go like this.

David Sheff : I thought we were close. I thought we were closer than most fathers and sons! Why? Nic Sheff : I felt better than I ever had, so... I just kept on doing it. David Sheff : This isn't us! This is not who we are!
