This will be rewritten. In fact the whole text block before that scene and referring the reward will be changed, as the idea will be Naira didn't even know what the prize it. Lina also doesn't know, and will meet the Wolf accidentally entering the wrong door in the prison.
It will be something like the horse guy escapes after Naira punched the sly host who tried to make her do it, and ran away keeping the prison door open. Then Lina enters the prison searching for her prize (as she completed the tasks but the host is nowhere to be seen), and accidentally got to the Wolf, whom she sets free out of pity—and then he destroys the fare, leading to one more Lina-Wolf scene in the very end.
