- "Right you are. With Henselt alive, Nilfgaard wouldn't 'ave it so easy in the east."
- —Rufus about eastern front
There are three possible endings to this secondary quest. To stay neutral, and let them reason on themselves. To help Manfred against Rufus, or Rufus against Manfred. If Geralt chooses to side with the Rufus, he will search Manfred's body and comment on his purse filled with Nilfgaardian Florens, stating his suspicions were presumably correct. However, since Manfred is a traveling merchant, his possession of Florens can be explained by trading with Nilfgaardians.
