"I'm terrified"

Rapunzel: I've been looking out of a window for eighteen years, dreaming about what I might feel like when those lights rise in the sky. What if it's not everything I dreamed it would be? 

Flynn Rider: It will be. 

Rapunzel: And what if it is? What do I do then? 

Flynn Rider: Well,that's the good part I guess. You get to go find a new dream.
