You both take the potion

As you both drink it you feel nothing at first. But a bit later you feel as if all the horniness was gone from you. Father Constantinus feels the same, the potion must have worked! Now, that you are both completely free of her influence, it is time to find evidence of her evil deeds. The inquisition will arrive tomorrow to investigate the situation. {if Julia home = true}Julia is still missing to your great concern... {endif} Father Constantinus tells you, ever since Sofia arrived, she had taken all the keys of the church from him and never allowed him to enter the underground rooms again. They were used to store wine and clerical belongings, she might have done something with them. You better check those rooms out as you have the keys copied already. You sneak into the church while Sofia is preaching outside. You go straight for the cellar without wasting any time.

Lily: Right, I am here. Let's open this door and take a look down below. This is the only entrance, if Sofia comes, I will be trapped down there... But I have ****, I have to find something to put her on trial!

You open the door and lock it back up after yourself. There are three doors there, which one will you open first?
