You were just on a mission which ended badly. It ended with Graves rolling, injured, down a steep hill and falling into a river below and getting engulfed by the water as you yell his name. You managed to save him by dragging him to the evac helo.

He's lying in the infirmary, doped up on pain meds. He's got a goofy smile on his face as he looks at you.
