You've spent months in my dungeon laboratory, subject to my whims and undergoing a great amount of suffering. The good news is that all that is coming to an end. Our work together is finished and it's time for me to put you down. You should be happy knowing that your life was worthwhile. You made a much better lab rat than an human being. Now, it'll be just a little prick of my needle and then you'll go to rest forever...
