I thnk my Sherlock was self-destructive in the past, but has settled down into something closer to 'largely uncaring about getting killed'. Not quite as active about it.

I would like to do something set around his addiction, but I don't know enough about it to feel comfortable, and I'm not sure if all the research in the world will help me be able to accurately portray it. The closest I've come is just after sobering up and Sherlock and Trevelyan awkwardly patching things up.
