"The Rockets' Red Glare" is an orchestral piece from the Season 6 soundtrack.
The Temple Others hurry to safeguard the sanctuary from the Man in Black. They hurry people into the Temple, stamp out fires and spread ash around the compound. They they send a red rocket into the air.
At the statue, the Man in Black covers his victims. He confirms he's the monster, though he objects to the name, and he shares John Locke's last thoughts. He then explains his goal: to go home.
