It seeems like at the end of every episode, there's a "mini plot twist" to end the episode with a bang. but theres also some really big ones that i never saw coming. The biggest ones for me was the revelation that Ethan was an Other, and that Charles Widmore and Mrs Hawking were Others on the island. im not including the introduction of flash forwards because a friend read spoilers about it and then told me, so i wasnt surprised. Any other big ones im forgetting?
