The door

Unbeknownst to Doe, the building she is in has not been expertly built. Many of the rooms have been built at an angle, including this one. It is most obvious when it rains or when they are cleaned. The water always builds up at one corner. With this room, the lower end is where Doe is sitting. So instead of there being a 50% chance of the bottle pointing at either her or the way out, you’ve got more like 75% chance of getting your way.

As the botte starts slowing, you’re hoping gravity will pull the wine in the bottle towards Doe. When it finally stops spinning it points to … the door.
Doe smiles and says “Looks like I’m free.”
You droop your head and sigh. Dammit, you were supposed to have your way with her, not let her go. But alas, you are a man of your word.
You fetch the keys and unlock her shackles. You walk with her through the dungeon, give her back her weapons, even present her with a horse to ride back home, or wherever she wants to go.

Before she leaves, she turns to you and says “For what it’s worth, I had expected worse from my imprisonment.”
Then her expression sours.
“Though I could have done without the sex.” She finishes.
You nod and reply with a single word. “Understandable.”
Then Doe spurs on her horse, and rides away. You never see her again.
