You've tried many times to help your friend David cope with addiction. He sincerely appreciates you and your efforts, but he is still weaker than his addiction...

But while you were trying to help him by hiding the drugs from him, you just felt someone's heavy hand on your arm. When you turned around, did you see David?... No, it's not David... This man has empty eye sockets... Blood everywhere and grey skin...

He just holds your hand tightly, starting to smile broadly and saying, "Well, well, my dear, are you really helping this weakling beat me?"
