Shawn isn't pleased that he has to leave his son with a neighbor, but he does come with minimal protest upon having had the situation explained to him.
Meanwhile, Robin puts on his mask and bodysuit, and Velocity begins the search.
It's dark outside, the sun obscured by clouds. The snowy wind whips at his hair, the cold stings at the exposed parts of his face, and he really, really hopes Armsmaster is safely inside somewhere.
(He would have called. If Armsmaster had been safely inside somewhere, he would have called them. Told them where he was, why he couldn't come back.)
Velocity starts running, and the wind and the ice do not touch him anymore, and the snow does not crumple under his feet, and he could almost go anywhere he wants, almost, but the world is still cold and the world is still dark, and he hopes wherever Armsmaster is, he can find him in time.
