Kotetsu definitely gets the feeling that he's being watched. He has good instincts for dangers and threats - he's had to develop such instincts as a hero, and especially as a hero growing weaker by the month. He stiffens slightly when he realizes that someone else is in the library with him, his eyes widening fractionally. But he doesn't call out first. He just replaces the book he'd been browsing back on the shelf, and moves a little more carefully when he sets off again.

It's a relief to have the mounting tension of anticipation broken by a voice. And for a moment, he even thinks that it sounds like a reasonably friendly voice...before he hears the claws. Even then, his first thought is "knife", because...well, why would his first thought be "claws"?

"What can I say?" He shrugs expansively, faux-casual, before glancing back over his shoulder. "I didn't see a closed...sign..."

He trails away in shock, his eyes widening much more noticeably at the sight of the creature at the other end of the aisle. Okay. This is new. This is not a good sort of new. He's not terribly afraid of crocodiles, as a rule (or is that a giant alligator?). So he has no idea why one might be in his dream. But it does look...very big and menacing, all things considered. All the moreso because libraries are supposed to be a place you go to in order to get away from crocodiles. Aren't they?

"...around here," Kotetsu finishes, somewhat awkwardly, after a very traitorous sort of pause. He follows that up with a most eloquent: "Um. Hi?"
