Keigo blinked, following Law's gesture to the painting behind him. A polar bear... He didn't even want to know how this guy was apparently acquainted with a damn polar bear, but the way he spoke was pretty convincing. No real room for deceit, or the guy was an insanely good actor... He decided to take his word for it. When he gestured towards the painting of his mother (or... someone who looked an awful lot like her), Keigo tensed. He looked back at the portrait, at the haunting smirk that still played at the woman's lips, and gave a shallow nod.

"...that one looks a lot like my mother," he admitted almost sheepishly, running his hand up through his hair. He rubbed at his scalp before looking around himself, maybe in the hopes that someone else would show up and confirm the situation for him. As firm as this guy was, Keigo was too cautious to really take the word of one man alone...

Still, he had a point. Keigo pursed his lips and stepped away from the painting, closer to Law. Close enough where he could really gauge just how impressively intimidating the man was. He sort of regretted it. "But I... uh. I don't intend to let that happen! If it's not a prank, then it's gotta be something else, right?"

Once again, he was leading the conversation, hoping that he wouldn't have to be the first person to suggest something crazy, like ghosts or demons or... something.
