if it cheers the gays up i'm thrilled

When reading the same scene from the book, the text gave me a feeling that his only concern was if they could find out the truth when watching Watson and the investigators, and he felt relieved when they left. This is how it goes:

"There I was stretched when you, my dear Watson, and all your following were investigating in the most sympathetic and inefficient manner the circumstances of my death...At last, when you had all formed your inevitable and totally erroneous conclusions, you departed for the hotel and I was left alone."

There is not much emotion in his narrative. It reads to me that at the moment the only thing he had in his mind was to conceal himself and not be found alive. His heart had no room, or so I perceived from the text, for the sorrow of Watson.

But in this show, on seeing Watson desperately looking for him and calling his name, he almost responded, but soon restrained himself.

When Watson saw his notes and started to cry, his eyes started to get tearful. He moved his eyes from Watson and took a few breaths to calm himself.

The show keeps the line of Holmes joking about how Watson and the investigators' very inefficient and erroneous investigations. He was still enjoying the scene and smiled. However, we can all see how sad he was in the meantime.

After that Watson finally left. He just stayed there and watched his dear Watson leave with tears welling in his eyes, but never fell. Just look at him: he was really struggling inside.

I watched this part so many times, it is just incredible.
