The portal is successfully closed, Caesar knows, as the lights from its edge and all of the monitors blink out of existence, leaving the moonlight from his windows being the only source of light in the room. Which is a good thing for Caesar, because he looks behind him just in time to notice a form of someone--no, a part of someone--on the floor.

Oh god. He just cut a person in half. Except it doesn't even look like half, and Zaknafein--he's finishing the job. It's a mercy killing.

Which is the last thing that goes through Caesar's mind as he stoops over and loses his dinner all over the floor to the side of him.

Dead, dead, he just--he just killed someone. Manslaughter. Accidental. The person just died. The non-sequitur thought of 'How will I get the blood out of floorboards?'

... or vomit.
