In the cutscene prior to the Long Night of Solace mission in Halo Reach, Jorge throws a briefcase down as they walk into the cave they are in. I always thought this was interesting because the camera seems to linger on the case for a moment, as if it was of importance, yet no one mentions it in the cutscene. What's in the case? Is it ever explained? Was there some cut dialogue that related to it? Maybe Jorge just took the Pulp Fiction briefcase, I don't know.
