Kitty Winter: Do you know what I haven't said to anyone in a really long time? I love you. Isn't that the saddest thing?
Sherlock Holmes: Do you know why most investigators fail?
Kitty Winter: Lack of elastics?
Sherlock Holmes: They refuse to extend their base of knowledge beyond the bounds of basic investigative procedures.
Kitty Winter: How did you get this address?
Sherlock Holmes: DCI Hopkins. He oversees the inspector you've been harassing, Davis.
Kitty Winter: I haven't been harassing anyone.
Sherlock Holmes: Yes you have, but with good reason. Davis is a good man, but a limited thinker, and he requires harassment.
