Geralt's strength came as a surprise - Bull hadn't had any reason to grapple with him before now and so hadn't had any real way of gauging what Geralt was capable of.

He didn't go far but he hit the ground hard, not quite catching himself. Bull used his own momentum to try to scramble back up. This time he stood but stayed low; his center of gravity could be a problem. Krem used it against him all the time. Pain in his ass.
