(Watson bothers Sherlock about the mess in his kitchen, and about how structure and order are good for recovery)
Sherlock: Without Andrew Fleming's reluctance to clean petri dishes the world wouldn't have penicillin would it?
Watson: Since the world does, (she holds up a container full of old food) do you have to grow it in your fridge?
Sherlock: (Huffs and walks away) Nine days, twelve hours, forty six minutes.
(Sherlock and Watson talk after getting another strong alibi.)
Watson: You're angry because that man and her husband could prove that they didn't commit a murder?
Sherlock: I'm angry because I've run out of suspects. At least for the time being. I liked that one too, oily.
Watson: He helps run a charity that dismantles landmines.
Sherlock: John Wayne Gacy gave his time to several charity foundations. Does that make him a good person too?
(Sherlock and Watson are "whore fishing" in the hotel's lobby.)
Sherlock: When the cat's away the mice will play. In this case the cat got it's skull caved in, and the mice are prostitutes.
(Watson walks into the room where Sherlock is sitting with a random trashcan emptied onto the floor.)
Sherlock: Borrowed our neighbors bin to test your theory about physical mess and it's correlation to relapse. I've been sitting here for hours and haven't felt any additional temptation to use drugs. We'll see how I am in the morning.
(Captain Gregson tells Sherlock that they have to wait for the FBI to finish with their suspect. And that they're lucky to still be involved at all.)
Sherlock: Oh yeah. By all means. Lets express our gratitude to the lurching inept bureaucracy that is preventing us from questioning a suspect who sits not ten feet away!
(Watson walks into the room.)
Gregson: Good, you're here. He's doing his tantrum thing...(leaves)
