Run after the Demo-Man and finish him off

From Create Your Own Story

Everyone else is distracted with their own defenses and you never let your prey get away from you so you run down the hallway shouting after the battered Demo-Man. You finally arrive at the battlements and see the Demo-Man... only he's glowing and has a vicious smile on his face. You se that he has been charged by a BLU medic and now you know that you're in trouble. You start firing your SMG at the glowing Demo-Man but he does not even flinch. Instead he shoots a pill-like object at you. It lands on your foot and 3 seconds later it explodes. Your legs have been separated from your body and now you crawl backwards on the ground using your hands, leaving a sticky trail of blood. The demonic Demo-Man stands over you and shouts, "Oh, looks like they're gonna 'av to glue you back together... in hell!" The Demo-Man then drinks his rum and smashes the bottle over your head.
