Jintetsu reeled at the thing Alice had summoned, instinctively stepping half in front of Marona to make her less of a target. Good grief, that woman was doing it again? He didn't hold with all this preternatural crap anyway, and the last time he'd seen her use her magic, he'd been very lucky not to be flattened by it. The screams and strange noises suddenly coming from inside the tent reinforced his anxiety, too.

Laughs or not, he wasn't sticking around to get killed. While Beetlejuice's attention was (hopefully) occupied with Alice and that unfortunate bystander she was apparently targeting (why, he didn't know or care), Jintetsu abruptly grabbed Marona by the wrist and started walking away from the tent.

Yeah, Flonne knew the girl, but like hell they were going after her. If she was still alive by the time they left the festival, maybe he'd leave Marona with her then.
