Even though he knows full well how Shockwave can be, and how easily he slips into a 'casual' gesture like an arm around his, it still seemed to take him by surprise. Like every time it happened. His eyes widen, looking down at their arms linked together and noticing that familiar white and blue paint. Trailing it back up to that familiar, smiling face.

Familiar, yet not so familiar.

"Uh."

When he sees the gesture, his gaze turns to the dance floor, then back to Shockwave, eyes slowly widening in slight panic. "I...can't dance." As if he had to put that disclaimer up immediately to not make Shockwave assume any less.
