I feel like Jester reeally wanted to buy that stone for Caleb but Fjord beat her to it. Cue Jester getting competitive and showering Caleb with gifts and presents and Fjord can't let that go unchallenged so they keep trying to one up each other. And the gifts get sexy. Caleb is confused but into it, and it eventually culminates in a threeway.
