If the immediate solution isn't some form of violence, Berserker doesn't really know how to deal with it. Not getting someone killed is certainly something he's capable of, but right now all he wants to do is kill. A silent death for the enforcer is what he was planning on until a wrench got thrown into his plans. All he wants to do is get out of here with Waver and make sure he's safe -- why the hell did he have to start feeling empathy for the other monsters? The fastest way to get what he needs is to play along.

So fuck it.

"We'll get them rounded up and be on our way...There's just one more."

He has the unfortunate fact of looking nearly identical to another dignitary from Aefenglom and Berserker doesn't want his actions to become a problem for Caster. The less attention drawn to him, the better. Instead of arguing or fighting, he simply walks -- not runs -- towards where he saw Geralt go off to. The alleyway...Nevermind that for the moment. He catches up to the witch.

"I owe you. There's one more that ran through the alley over there and I don't think they'll listen to me."
