[The sound of something hitting the ground catches Shun's attention, and his attention snaps to that direction as if he's expecting some kind of threat. When he sees the yellow helmet, though, his gaze moves to the figure behind it...and the immediately obvious lack of a head. Though he draws back slightly in surprise, it doesn't last long - he's met weirder here already - and as soon as he notices there's humans who seem to have seen the impact, he heads over, grabbing the helmet on his way past.

Clapping his hands sharply to draw the attention of the crowd and then shooting a glare that sends several of them scurrying off, Shun shoves the helmet at the woman before putting himself between her and what remains of the onlookers. He's not exactly pushing her away from them, but there's definitely an urgency about his manner that says he's trying to hasten her on from the people who actually saw what happened.]

Put that thing back on before anyone else notices. They'll forget about it in a few minutes anyway, but in a place this crowded, the less attention you draw, the better.
