He tilts his head now in absolute curiosity as instead of staying right there in front of him face to face he moves. He's now prowling as he stays within reaching distance but walks around Allen to look for any other changes. He's reaching out to touch those twitching feathers again each time they do in fact twitch. He's right, that itself doesn't feel like Innocence.

But that brings up a very good question and his grin is still present as his amused tone filters into his voice, "Then, those aren't creatures that are wandering around as carnival folk. They are human but with changes. I was wondering why there wasn't anyone ordinary around."

It's why he's preying so much. Allen doesn't seem like himself and he knows him almost better than his comrades. He can read his expression easily. Yet like always Allen's expressions bring out the best in Tyki as his grin fades with a small blink, "You mean like an extended vacation? Or are you happy to be rid of me as soon as possible?"
