Delta goes to the water's edge, Rein can still hear/see her from there, although they can't see her.
"Karp...? Is that you...you can come out..."
An old woman siren comes out of the water and sits in the shallows with Delta
Karp: "Princess! I knew you'd be here, you always are..."
She laughs a little "Awe, don't tell me I'm that predictable..."
Karp: "Princess...you know why they sent me here, don't you?"
"I...not really..."
Karp: "The king and queen are worried about you...everyone is worried about you..."
"B-but I'm fine! Really-"
Karp: "I know you can't do it, Delta."
