The conversation between human and AI assistant.
[SPOILERS] Why did Mary save Sherlock from the bullet in the first episode of season four of Sherlock?
Why do you think Sherlock broke the fourth wall and spoke directly to the audience at the end of the episode?
I think that Sherlock broke the fourth wall to emphasize the themes of the episode, such as the importance of human connection and the consequences of one's actions. He wanted to make sure that the audience understood the gravity of the situation and how it would impact the rest of the season.
