You tell Windcaller that you think his skills would make a great addition to your party, and ask if he is sure he doesn't want to come on more adventures with you.

Windcaller: "I'm... sure of it. My destiny lies here. Going on adventures just... doesn't feel right."

You tell him that it's too bad, and ask if he wouldn't be up for even a little adventure with you and Moonflower in bed tonight.

Windcaller: "Ah, w-well... um... that's, uh... that's... not the same..."

As Windcaller begins to shift awkwardly on the sand, Moonflower lands nearby on the beach, and trots toward you.

Moonflower: "I'm here‼ Oh, cool! Are we makin' castles?"
