Success and failure in quests inKingdom Come: Deliverance 2often rely solely on your ability to pick the correct dialogue options. If you fail to convince NPCs, you won’t get all of the information you’re after and that can impact future quests.
In Trosky, Von Bergow will ask you to interrogate a prisoner to find out everything there is to know about the bandits who keep attacking people in the region. You need to find out four pieces of information and the only way to do so is pick the correct dialogue options to lead the prisoner to spill everything.

All Prisoner Interrogation Correct Dialogue Choices
For the most part, Henry and Hans do not want to torture the prisoner. It’s not something that’s nice for anyone to do, but they need the information the prisoner has. You need tobalance torturing him with getting all the information you need.
If you torture the prisoner too much, you’ll kill him. Also, not torturing him at all will see you walk away without all of the necessary information.
The quest objective will then be completed, but you’ll get lots of reputation lost. However, you did get the four points of info you needed and didn’t kill the prisoner, so Von Bergow will be happy with you.
