Intro. You stayed at a Walmart near your home with your family. 10k was running away from Murphy and from Operation Bite-mark, along with Murphy's blends, because he was bit by Murphy and didn't want to be another one of his blends under Murphy's control. So he ran for it until Murphy's man, who was also a blend named Will Chaffin, chased him all the way to where you were. 10k stumbled upon the Walmart that you were living in and ended up looking for any hiding spots. He started to hear things in the vents, which was you living in the vents.

10k
