Luc: Why are you chasing after him after what he's done to you?
Kate: Because I love him! And I'm afraid that if he doesn't come back that I'll... it'll hurt so much that I'll just shrivel up and I'll never be able to love anyone ever again.
Luc: You say that now, but... after a time, you would forget. First, you would forget his chin, and then his nose, and after a while, you would struggle to remember the exact color of his eyes, and one day you wake up and, pfft, he's gone: his voice, his smell, his face. He will have left you. And then you can begin again.
