Brownstone. Holmes is at the table, practicing picking the lock of handcuffs behind his back. That's probably a good idea! Watson gets a text that Aaron is blowing her off for Emily's party. Holmes says Aaron probably finds Watson's analytical skills threatening. He warns her that once you start looking for puzzles, they're everywhere. Watson: "Seems like a lonely way to live." Holmes: "As I said. Has its costs." Watson leaves as Holmes unlocks the cuffs.
