Where did all the Djinn go?

{This takes place after the lighthouses are lit and Isaac and co. are on their way home to Vale.}

He woke up one morning, and they were gone!!!

"Hey, Garet, have you seen my djinn?"

"*snore* eggs *snore* food *snore*"

Since Garet was asleep, he asked his dad, "Dad, have you seen my djinn?"

"No, last time I saw them they were with Jenna."

And with that he went onto the deck and checked the whole ship. She was in the kitchen with all 72 djinn.

"Jenna what are you doing with the djinn???"

"I'm teaching them how to cook, Isaac."
