Dharma Initiative
The episode contained two pieces of music from the 19th century German composer Johannes Brahms: his Piano Quartet No. 1, Op.25 in G Major: III. Andante Con Moto-Animato and Piano Quartet No. 1, Op.25 in G Minor: II. Intermezzo: Allegro Ma Non Troppo-Trio: Animato. Also in the episode, someone is seen holding a Dharma Initiative tea bag, a reference to the mysterious organization on the science fiction series "Lost".
