Sherlock: Oh enjoying the thrill of the chase is fine. Craving the distraction of the game, I sympathize entirely. But sentiment, sentiment is a chemical defect found in the losing side.
Irene Adler: Sentiment. What are you talking about?
Sherlock: 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?
Sherlock: No. Because I took your pulse.
