There's a slight rumble and a hand snaps up to catch Soundwave's as he touches the mask.

A pointed pause as the battlemask below his visor parts revealing chapped, split lips and pale skin. Soundwave's hand is then placed neatly against his cheek.

He's not sure what makes him do it, but it is an impulse- something strange and overwhelming.

As quickly as it happened, he lets go and turns to sit down. To mull over the why. The mask snaps shut again.
