Plot issue (spoilers)
So they have the key to the basement, leave it open knowing Cloude intends to come down and get more champagne. Surely they knew could have seen that Claude would suspect something? No?
shareThey had the key to the basement, the original plan being for Devlin to check it out, return the key to Alicia, and for Alicia to replace the key on Sebastian's keychain that evening. There was no thought that anyone would visit the wine cellar that evening, because, after all, Joseph would want to make just one trip down there, Sebastian would want to unlock the cellar just once, and so they would have brought up plenty of champagne, enough (by their best guess) to comfortably serve all the guests.
That they did start to run out of champagne takes them completely by surprise and makes the trip to the cellar perilous and suspenseful.
Prepare your minds for a new scale of physical, scientific values, gentlemen.share
