Something brought you here, Flynn Rider. Call it what you will: Fate... Destiny...
So I have made the decision to trust you.
But trust me when I tell you this: [pulls Flynn close to her face with a glare] you can tear this tower apart brick by brick, but without my help, you will never find your precious satchel.
[clears throat]
Let me just get this straight. I take you to see the lanterns, bring you back home, and you'll give me back my satchel?
I promise.
[Flynn looks at her suspiciously]
And when I promise something, I never ever break that promise.
Alright, listen. I didn't want to have to do this, but you leave me no choice. Here comes the smoulder.
[He puts on a pouty face, hoping to charm Rapunzel. Her stare just hardens.]
This is kind of an off-day for me. This doesn't normally happen. [gives in] Fine! I'll take you to see the lanterns.
Really?! [She jumps in excitement, letting go of the chair Flynn is sitting on. Flynn falls on his face.] Oops.
