"Through the Looking Glass" is the twenty-second episode and season finale of the third season – sixty-ninth episode overall – of the ABC television series Lost. It was written by co-creator/executive producer Damon Lindelof and executive producer Carlton Cuse, and directed by executive producer Jack Bender. When the episode first aired on May 23, 2007 in the United States and Canada, it was watched by an average of 14 million American viewers. Like the previous two season finales, it was two hours long with advertisements, which is twice the length of a normal episode. It was split when released on DVD. The season finale was critically acclaimed and the episode has garnered a number of awards and nominations. The episode begins on December 22, 2004, ninety-two days after the crash of Oceanic Airlines Flight 815. The battle between the crash survivors and the dangerous and mysterious island inhabitants referred to as the "Others" comes to a head as ten of the Others ambush the survivors' camp and are subsequently killed. Meanwhile, Jack Shephard (played by Matthew Fox) leads most of the survivors to the island's radio tower to communicate with a nearby ship. This is the first Lost episode to feature flashforwards, as opposed to the customary flashbacks. Actor Dominic Monaghan makes his final appearance with main cast credit as Charlie Pace in this episode.
