Greg nodded and turned around to get a glass of water. His mind though, was occupied with the thought of the bath. They were both men, it shouldn't be anything difficult, but he was hesitating, for some reason. He grabbed some glass that looked clean and filled it with water, then headed back to Sherlocks room.
"Here." he said and sat down at the side of the bed, holding the glass out for him to take. He looked him over, relieved to see he was doing much better. "Maybe, if you will eat a little, we could try with the bath." he said, smiling, a little mischievously. But he really was thinking it would be easier and better if Sherlock ate a bit. He needed the strength, after all. Even if he didn't like it. Also, he was getting a little hungry himself, and tired, but to the latter he was used to. "We'll have to make sure to keep your arm out of the water, though." he added.
"And once you're up and awake, I've got a case for you." he said, hoping, this might keep Sherlock from protesting too much.
