Yup, you just have to leave every key alone, because you're right, Rebelicious; once you've picked them up, you've committed yourself.Kreador Freeaxe wrote:You only use them automatically if you take them. You never have to take the keys, except at the church, and that one you can pick the lock before you get the quest (and thus the key).
Strange is, Kreador, that you do not need the key for the church at all; you can kill Julian, then go to father Tyrus for the first time, and you'll still receive your money and experience points for the quest, eventhough technically you never received the quest. Well, no, that's not quite right; you still have to ask first for a job, but you can do that after already having done the job.
The only difference is that in the conversation with Julius you won't see any dialogue options involving father Tyrus popping up.
