Oh, you three.... :'(
We've talked before about Sherlock's seeming lack of a sense of self-worth, haven't we? I think that's why half the people here always go around thinking he's in need of a good cuddle...
Lol... this season he definitely needed a cuddle... it's surprising because in the episode, it seems like no one checked on him other than Mrs. Hudson. Mary sacrificed herself for him. That would mess with anyone's brain and it doesn't look like anyone even checked on him. John said no one had seen him for weeks. You have a friend who you know was drug issues and that suffered a trauma and you left them alone for weeks? I just can't imagine it. I would have thought Molly or Lestrade knowing him would have forced their way in (although I'm sort of glad Lestrade didn't... would have been a completely different show lol). Shoot, that Mycroft didn't put his foot down over the drugs is surprising.
I've always thought Sherlock needed a friend that wouldn't get pissed off and walk away. Someone who would stay and fight back when he was being an idiot.
I agree, I think his younger years must have been difficult. There is something the writers are implying. Just not sure what the extent is.
I don't know that feeling sad, lonely and guilty mean suicidal though. I don't know. If we get more episodes, I'm sure Mycroft will let out what happened in the past...
