IAWTC, especially the part about BBC!Sherlock. He's kinda childish and a brat but you can see that he feels like an alien among "normal" people which makes him feel superior but also makes him eternally frustrated and confused by us. And for all his bravado and "Ew, sentimentality!" he still gets hurt and feels embarrass and LOVES because ultimately he's still human.
You know while writing this ramble out, it occurred to me that Sherlock is kinda like Castiel. No wonder I like him so much :)
