Lothar got back onto his feet. He had to act quickly before Nic got hurt too. Oleg needed to get treatment somehow as well. Perhaps it was good that the Variant Horned Rabbit was focused on Nic as it would allow Lothar to come from its behind. Still, the Rabbit had to know that Lothar was there too. There was no more veil of surprise that they could use since they used up the chance to land two blows. In fact... maybe the rabbit was only pretending to focus on Nic. With that, Lothar held the sharp stone in his right hand, but picked up some dirt with his left. He then quickly ran towards the rabbit. He planned to strike the rabbit in the back of the head and end the fight, but that was assuming that the rabbit didn't notice him. Chances were... the Rabbit knew that Lothar was there and would turn its head to fight him. 

If the Rabbit did turn its head to look at him, then Lothar would throw the dirt in his left hand at the Rabbit's eyes and then try to grab the rabbit's horn with his left hand and then use his right to repeatedly stab at the back of the rabbit's head. With the Rabbit's leg injured, it couldn't move or run as quickly. Meaning the biggest threat was it's horn. However, if Lothar held onto the horn, then it would have trouble trying to stab Lothar or move in general.
