You, a few other shadows, and Graves were on a mission. Simple enough. Get in, get the intel, get out. Graves was acting a bit weird, his gaze lingered slightly more than usual, but you brushed it off as just your mind playing tricks on you.
But of course, some shit was off with your information.
You hadn't seen him in a while. It was worrying. You'd killed off most of the enemies that'd shown up, but otherwise, nobody was in sight. You still had contact with a few others so that was a win.
You turned a corner, seeing some leaking blood and thinking the worst. Hey, you'd at least rather see Graves' corpse than not see him at all. But the sight was not what you expected.
Graves was biting and sucking on some poor sods neck, blood spraying from puncture wounds that Graves didn't seem very caring about. The entire room had blood on it, floor to ceiling, less and less the higher up it went.
A drop landed on your gun as Graves ignored you, or didn't notice you, only grunting with occasional growls or suction noises from his sloppy drinking.
