His smile tugs a little wider at her teasing. Being able to give that impression not just to anyone, but to someone as smart and long-lived as Yennefer, gives the warden a little notch of pride.

Though that feeling changes into confusion as he watches her brow get heavy, troubled. Part of him starts to wonder if she's tempted to put an end to all of this. It wouldn't surprise him. He might be a part of it, but that doesn't mean he agrees with everything they're doing here. Still, he'd rather not have to come into conflict with Yennefer, so he's glad that expression passes and is replaced by a smile.

Taking her hand in his, he lifts it to his lips and kisses her knuckles in a silent reciprocation of her affection.

"I'd better not disappoint, then." He starts up the jeep and watches the dilophosaur chirp and dart away before he gets them moving again. "I'll show you the last few dinosaurs we have on the island, then... Well, there's not much to eat here. I wouldn't want to put you through the canteen's food, and the restaurant isn't open yet. I'm afraid the most I could offer you is a drink to cap the day off."
