Greg steps back and groping his crushed hands, which morphs back to human hands, but his healing ability slowly heals the crushed bones, but the flesh was not yet healed because the Wolfsbane is affecting his ability.
Jester just stood there waiting for Greg's next move, "Well what now? is that all you got," Jester taunted, on the side, Liza was watching Jester, she was a bit worry, although Greg didn't notice, his attack was actually able to hurt Jester's hands a little even after using Chaos force to block the attack, she knows that even though Jester's hands were healed quickly because the injury was too shallow, unlike Greg's but she was sure that Jester's hands are still numb from the attack, that is the reason why Jester couldn't retaliate, he was just acting tough to buy some time for his hand to recover.
