BSG Spoiler List
• Lightsabers will debut this season.
• Cylons build a fully armed and operational battle station. From a distance, it looks like a moon.
• A Colonial Raptor lands in a new planet and one of Galactica’s pilots gets attacked by some kind of bug that attaches to his face.
• Galactica flight deck crew install a new weapon in a Viper apparently called “Death Blossom.”
• Galactica has a problem with its heating system, but another Colonial Raptor lands in a forest planet to discover a large population of small, bear-like creatures living on trees. They kill them all and make nice coats for everyone in the ship. Colonist rejoice. Viewers too.
• In the final episode, we discover that President Roslin is really a lizzard with fake skin (that was a given, quite frankly.)
• Galactica then arrives to Earth, only to discover a world full of monkeys. They also kill them all.
• In the final scene, Starbuck and Apollo discover the hand and the head of big woman statue, made out of copper, coming out of a beach’s sand. They don’t know what the frack that means, but finally make love next to it.
