"Did you?" Percy was surprised that he'd forgotten this. "Oh yes! That's right! At the end of September! I was joking with you about Comet being a guard dog." He smiled a little, hoping the mention of Oliver's puppy would bring a smile on his friend's face.
Percy drank some of his coffee, trying to understand. Whenever Oli would get this way, back in the Real World, it was usually something that had to do about losing a match. Or maybe he was just homesick for this mother and sister. He grimaced, trying to think of what to say. "Well. That sounds fun?" he said, hopefully. "An expedition is exciting. And I hear they've been selecting teams for regular Quidditch competitions."
