Joan: *attending to Sherlock's wound* This is stupid, you should be in the hospital right now.
Sherlock: I told you there isn't time. Besides, what's the point of living with a former surgeon if she can't stitch the occasional bullet hole?
Joan: The muscle in your shoulder is shredded, okay? You need to be treated for the pain.
Sherlock: May I remind you I'm a recovering drug addict.
Joan: May I remind you there is such a thing as non-addictive pain killers?
Sherlock: How good could they be if they're non-addictive?
