[Texting? It's a bit beyond her abilities, considering typing mechanisms of any sort weren't exactly available in her tower. Not to mention that typing feels doubly unnatural with the alphabet all out of order and spaced strangely. Initially, the other two options aren't much better for her, and it takes some fiddling around before she gets the audio function to turn on.]

Um... hello? Am I doing this right? Can anyone hear me?

[Well, assuming she's using it correctly, here goes nothing.]

My name is Rapunzel, and while I'm sure that gigantic, talking, magic-living-statue person meant well, I really, really can't stay long. You see, I have a very important thing I recently set off to do, and if I don't go right back to take care of it, I may never have a chance to again... [She mumbles the rest of the sentence.] and I've kind of been waiting my whole life for it. [Ahem.] So, if anyone would be so kind to tell me how I could possibly return home, I'd be really appreciative.

[There's a small moment of thoughtful silence.]

But before I forget, by any chance, did someone by the name of Euge-- um, Flynn Rider get here before me? I know it might be a bit of a stretch, but I thought it might be a good idea to check.

[In all honesty, Rapunzel would be relieved to see a familiar face in this strange, enormous, intimidating world. That said, if there is some sort of hidden way back home, she'd need to make sure Flynn could return with her.]

Okay, I think that's everything I wanted to ask about.

...And I really do hope this strange thing is actually working and that I haven't been talking to myself this entire time.
