In AOTC, when C3PO first sees Anakin at the homestead, he exclaims, "Oh, the Maker!"
Fast forward two episodes to ANH. As C3PO is being lowered into the oil bath, he exclaims, "Thank the Maker..."
So, at what point did this droid find religion? Or is he assuming that Anakin poured the oil in that tub a long time ago? or does he know somehow that Luke is Anakin's lil' boy, so in a roundabout way, Anakin (the Maker) is indeed responsible for the oil bath in ANH?
