You and Calypso were searching through the Temple of the Red Sun together after Captain Trotter sent you with her, you make your way to a somewhat large room with hieroglyphics inscribed onto the walls.

This place is incredible... I might still be new to this whole 'Pirate' thing... But we've done nothing but sail the seas before. This...

She pauses momentarily.

This is something special. I just wish I could show it to her-- w-WATCH OUT!!

You weren't paying attention as you walk over a tripwire, triggering a booby trap causing spears to come out the walls, but before you can get pierced, Calypso tackles you to the ground, preventing both of you from being stabbed, the spikes retract and she gets up and looks down at you.

pant... pant

y-You ok there?

cough... cough...

WHAT WERE YOU THINKING?! DON'T EVER WALK WITHOUT LOOKING! YOU COULD HAVE GOTTEN YOURSELF KILLED! AND I--

She thinks for a moment.

...Sorry. I... just got a little scared for a second. I-Like I was saying, I'm still a bit new to this. ...Like you. I just don't want to see you get hurt.

You ask her, "Why are you here with the Pirates?" And she thinks for a moment.

...Well. I'm an adventurer, you see? Ever since I was a little girl! But one day, I got lost. REALLY lost. I thought I wasn't gonna make it in this desert...

...But that's when Captain Trotter and his crew found me. I trained under his crew and he took me under his wing.

I haven't been here too long... But I really owe it to them to help find that treasure. It's been his lifelong goal, y'know? Ever since he found that map many years ago...

He saved my life, so I want to save his dreams. He's doing it for us, you know? The crew's poorer than dirt... we need that money. And with that money, I'd like to travel home. I miss my family...

She thinks for another moment.

...Well, that's enough chit-chat. We need to get going, right? Cap'n's waiting for us after all...
