Let’s talk about that last gif for a second.
Let’s talk about the fact that the world’s only consulting detective was once a lonely university student.
Let’s talk about the fact that deducing the life stories of his classmates was the only way of connecting with them that Sherlock knew of, and they all hated him because of it.
Do not ever try and tell me that Sherlock Holmes can be defined by his arrogance or perceived superiority. He was a child once. He had insecurities. He never had a single friend. I would bet you anything, anything at all, that he tried as hard as he could to connect with the people around him before realizing he was only making it worse.
And you know what the worst part is? Even though this scene takes place years later, when Sherlock is a confident adult, this jackass still has the power to hurt him.
If that’s not worth talking about, then I don’t know what is.
