The assassin turned his shoulder, lifting his Shardblade, preparing to thrust. There, Kaladin thought. He could feel what would happen. He would twist around the strike, bringing up the butt of his spear. It would hit the assassin on the side of the head, a powerful blow that even Stormlight would not easily compensate for. He'd be left dazed. An opening.
I have him.
Somehow, the assassin twisted out of the way.
He moved too quickly, faster than Kaldin anticipated. As quickly... as Kaladin himself. Kaladin's blow found only open air, and he narrowly avoided being run though by the Shardblade.
