Watson: Well, it certainly sounds like you had feelings for her.
Holmes: Perhaps but... nothing so mundane as love. I was adrift back then. I had-had no purpose. My so-called peers made me feel that that might always be the case. Abigail, she gave me a gift. A view inside a mind capable of murder.
Watson: So she was your first.
Holmes: Killer, yeah. Without intending to, she-she helped me understand who I was and-and what I might do with my life.
