Before coming to Credit Dauphine, Jack worked undercover for SD-6 at Jennings Aerospace. This company is used by Sydney in her alias on The Abduction episode.
The song being played in the concert while Sydney slips the sleeping drug into the British gentleman's drink is the Stokowski transcription of JS Bach's "Sleepers Awake" cantata.
