But also so damned destructive

Nina: What happened?
Thomas: She walked into the street and got hit by a car. You know what? I'm almost sure she did it on purpose.
Nina: How do you know?

Thomas: Because everything Beth does comes from within, from some dark impulse. I guess that's what makes her so thrilling to watch. So dangerous. Even perfect at times. But also so damned destructive.

Nina: Was it right after we saw her?

Thomas: Wait, wait, wait. This has nothing to do with you. It's not your problem, so don't let yourself be distracted. This is your moment, Nina. Don't let it go.
