[Well. Sebastian supposes he is, technically, capable of such a thing. For a moment he doesn't move, just continues to smile at Goku, but then he walks out onto the ice - not wearing skates but somehow managing to keep his balance just fine - and grabs hold of one of Goku's shackles rather than one of his hands before pulling him to his feet.
Sebastian's not ungentle about it, exactly, but it's a firm action, like he's not the least worried it might hurt. He doesn't let go of the shackle immediately.]
