YMMV / Lost S03E22 & 23 "Through the Looking Glass"

• Memetic Mutation:
  • "NOT PENNY'S BOAT" has become a shorthand for completely breaking down and crying in response to a television scene.
  • "We have to go back!", especially among fans who wish for a continuation or spinoff of the show.
• Signature Scene: The episode contains two of the show's most famous scenes.
  • Charlie's death, especially when he warns Desmond "NOT PENNY'S BOAT" by writing on his hand.
  • Jack meeting Kate at the airport, with him desperately trying to convince her that they need to go back to the island.
• Win Back the Crowd: After what many found to be an underwhelming season, the final twist of Jack's flashforwards convinced enough people to tune in for Season 4.
