They were all supposed to be listening to a Christmas broadcast by Mrs. Weasley's favorite singer, Celestina Warbeck, whose voice was warbling out of the large wooden wireless set. Fleur, who seemed to find Celestina very dull, was talking so loudly in the corner that a scowling Mrs. Weasley kept pointing her wand at the volume control, so that Celestina grew louder and louder. Under cover of a particularly jazzy number called “A Cauldron Full of Hot, Strong Love,” Fred and George started a game of Exploding Snap with Ginny. Ron kept shooting Bill and Fleur covert looks, as though hoping to pick up tips. Meanwhile, Remus Lupin, who was thinner and more ragged-looking than ever, was sitting beside the fire, staring into its depths as though he could not hear Celestina's voice.
