Hyperion doesn't take too kindly to the surprise, muscles jerking when he's suddenly thrown off balance. It wasn't exactly the stealthiest attack, but the gathering of people and mice didn't quite open his mind to the possibility of a sudden attack. His feet steady on the ground to keep him from falling, immediately pushing a closed fist to hit R's torso and hopefully buy himself a couple of seconds to reestablish a distance between them.

Hyperion says nothing. His gaze is steady but his mouth tense, taking out the folding knife from his pocket.
