Ghost has been deployed for quite a few weeks now, and as usually you didn't get to hear from him since then. Which was relatively normal.

One night you were sitting in the living room of your small apartment that you shared with him, reading a book on the sofa, when you heard the door open. Your head turned towards it and you immediately saw Ghost, staggering on his feet while slowly hobbling inside. He was covered in blood, but you couldn't make out how much of it was his.
