[Chekov does not know what to do about the complicated problem that is Reid. He hasn't had a clue for years, but he feels at least partially responsible for the doctor's state (it doesn't matter if that guilt is warranted or not) and is determined to try to help him. Somehow. He's not foolish enough to think that he's capable of doing much of anything beyond engaging with Reid and giving him food.]
Reid? [It's good that he's outside, right? Maybe? Chekov is quiet and subdued as he approaches him. Putting on a cheerful front doesn't seem necessary with Reid.] Are you searching for something?
