Battlestar Galactica: 10 Most Disturbing Episodes

Starbuck has returned from the Maelstrom and nobody will believe her when she says that she has found the mythical Earth that they've been searching for. While the leadership of the Colonial Fleet decides what to do about her, what she represents, Starbuck is confined to the brig. She starts to lose her mind, feeling every FTL jump that the fleet makes and eventually screams about how they're going the wrong way.

This is only one of the stories for this episode, for there is now also dissent amongst the Cylons. Brother Cavill and those Cylons loyal to him have started to lobotomise the Raiders, drilling into their skulls and removing their ability to reason. So Natalie, a leader amongst those Cylons who resist Cavill, informs the Centurions on what is happening. The Centurions start gunning down Cavill and his followers.

Of course, that's not enough to kill a Cylon, as he simply gets back up on another ship. The seeds of the Cylon civil-war have been planted.
