The two droids are still walking, when a person, surrounded by light, suddenly appears in front of them. Threepio, terrified, exclaims: "Oh my!! A hologram!!" But the person says: "Do not be afraid; I have good news for you: there is great joy coming to the whole people. Today in the city of David a deliverer has been born. And this is your sign: you will find a baby lying wrapped in his swaddling clothes, in a manger." All at once there are even more luminous persons, and they are all singing: "Glory to God in highest heaven, and on earth his peace for men on whom his favor rests". "Excuse me" Threepio says, "I'm only a protocol droid and not very knowledgeable about the things you are talking about." But the luminous persons suddenly disappear. Artoo whistles in amazement. "I agree with you Artoo!" Threepio says. "Quite impressive indeed!"
