Bottle of 33

[Sweet Tea]

I gave old guy his bottle before the holy slip day. Am I gonna have to start the whole game over?

No, you don't have to. You need to do something for him to leave and the wine has nothing to with it.

Solution:
You need to fill up a water bottle with water at any of the toilets and pour the water at the huge doors leading to the courtyard. (A marking will appear once you're near the area.) Next, you need to pull out the plug for the christmas lightings and he will go over to your area. Once he slips and falls, use telekinesis to make the icicle fall on him.
