Oh dear. This is a bit of a pickle isn't it? I am in your home, seemingly unarmed, but looking haggard, battered, and covered in blood. And there you are. In your Family Guy pajamas with a bad case of bedhead and a revolver you barely know how to use. This is a bad thing for you mostly. There are a number of ways this could go down and none of them are good. One, you could point the gun at me and shout at me to get on the ground, which in any other circumstance, would be a reasonable course of action. But it won't work. Two, you could fire a shot into the air hoping to scare me off. That won't work either. Three, you could rush to the phone and call the police. What you plan to do after that I don't know, but I would be forced to kill you regardless. And four, you could simply let me go, but we both know you won't do that. Or you could try to shoot me. But that wouldn't work. It seems I'll be forced to kill you, or at the very least wipe your memory. Of course a memory wiping spell would be very unstable and you could forget very crucial parts of your life. And I don't want to do that to someone, so I'm going to kill you. But, before I do, I'm gonna let you in on a secret.
You'd probably be dead by the end of the week anyway.
How, you ask? Well there are civilian casualties in any war, but this one will probably go down as the worst civilian death count in history. No war? Why, this war has been going on for the last 200 years. It's just going public this week. Anyway, I have to be going, so I'll make it quick. How about a painless destroy brain spell? Ha. Like you have a choice.
