Viktor doesn't want to be carried--Viktor wants Jayce to stay here with him, because he made a promise. If he can't do this, when they're ostensibly not in any real danger (well, he can't be sure of that, but his apathy makes him largely unconcerned, at the moment), how can Viktor trust him to fulfill his most important request, if the time comes?

"You don't understand. I don't want to--to fight anymore."

But, again, if Jayce wants to physically overpower him, there's not much he can do about it--even less when he materializes the hammer. This close, he wants to marvel at the intricate construction of it, but all it does is rekindle the well of anger in the pit of his stomach.

"What are you going to do with that?"
