John: Hello, Mark. If you are so sick then why do I have so many photos of you up and about? Let's put your so called "illness" to the test. Right now, there's a slow-acting poison in your veins. The antidote is inside the safe - the combination to the safe is written on the wall. Hurry up and program it in but watch your step.
[Mark steps on one of the many pieces of broken glass scattered on the floor]
John: By the way, that's a flammable substance smeared on your body, so I would be careful with that candle if I were you... or all the people you've burned with your act just might have their revenge.
