Irene Adler: No such thing as too much.

Irene Adler: Sentiment. What are you talking about?
Holmes: You.
Irene Adler: Oh dear god, look at the poor man. You don’t actually think I was interested in you? Why? Because you’re the great Sherlock Holmes? The clever detective in the funny hat?
Holmes: No. Because I took your pulse. Elevated. Your pupils. Dilated.
