My roommate kills people as a hobby

So, there is this game called Assassins. My hall is playing it and the game has had some interesting ramifications. This is how it is played: each person is assigned a "target" who they must kill. No one from the hall can see you do it and you cannot kill them in their own room. You must touch them on their back with a spoon and say "I killed you." Hence, the way to survive is to constantly be in the company of someone on the hall.

That said, I have acquired two shadows that accompany me while I use the toilet, take a shower, or travel anywhere really. It's like I have two little pets... except they are skilled assassins who have succeeded to be 2 of the last 4 still in the game. There will soon come a day when my two shadows hunt each other. This is the day I fear.
