Chase had probably gone home instead of going to get the file, in which case, he really should have just said he was going so that Foreman didn't waste his time waiting. He heads down some twenty minutes after Chase left, having decided that he'd clearly skipped out early.

He's heading through the stacks of old files looking for where the patient's would be located when he hear rustling and wonders if Chase is actually down here. He furrows his brows as he moves through to the next row and peers down and, there's Chase, standing reading a file that doesn't look like the patient file.

"Am I interrupting?" he asks, his tone suggesting that he obviously must be, given the fact that Chase is sneakily reading alone in the basement.
