Why Lost's two-part Season 3 finale still resonates

A rewatch of Lost's two-part Season 3 finale, "Through the Looking Glass," shows why the ending remains so affecting: Charlie (Dominic Monaghan) dies in a sacrificial moment that feels prepared for rather than arbitrary. Desmond Hume (Henry Ian Cusick) has visions of Charlie drowning, and Charlie's choice ensures Claire (Emilie de Ravin) and her baby Aaron can live.

The episode also delivers other major beats — Naomi's true identity is revealed, tensions flare among Juliet, Jack, Sawyer and Kate, and Jack's fragile mental state becomes a central concern — yet the hour still feels cohesive despite the many threads. Both parts end on brutal cliffhangers.
