John Lock's FAKE twin BROTHER on the beach!!

This is QUITE big!! I have DISCOVERED that Lock's FAKE twin brother was ON the beach during THE funeral!! IT's NOT Lock because Charles SAID to Lock (who was beaten UP by Echo) "Oh, that's right, YOU weren't there FOR the dramatic arrival at THE funeral"!! This IS Big!! I bet Lock's TWIN will be very central in SEASON 5!! But Charles knew THAT it wasn't Lock, so this is BIG!! I bet it's their LITTLE secret! I bet Charles and the FAKE Lock have a SECRET affaire!!
