"Oh wait," Percy said with sudden realization. "I remember that night, I think. You got so bladdered that I needed to take you home." He frowned, looking sadly at Oliver. This kind of scenario happened nearly every time his friend lost a game, and whenever it did, it worried Percy. Quidditch was a great sport, but Percy didn't have the same intensity for the game that Oliver did... Oliver identified himself with the game, and when he lost, his mood would plummet. It wasn't healthy. But then again, Percy had a similar passion for his work at the Ministry of Magic, so he had little room to pass judgment. Time had mellowed out both their obsessions, however, so by Percy's time, it wasn't nearly as bad as it had been, before. [OOC: I hope this is a correct assumption of Oliver's behavior]
Percy tried to hide the smile when Oliver hugged him again - he didn't have much physical contact in the village and it felt comforting. "Thank you. I have two daughters. The first, Molly, was born in 2004, and Lucy was born a few years later. It's terribly confusing, and a lot to swallow, especially all at once. But believe me, there are even stranger things in this village."
Seeing how Oliver began to panic, Percy placed a steadying hand upon Oliver's shoulder and told him, "It's alright, it's okay... what happens here has no bearing on the world where we came from. We're brought here and whenever we go back, it's as though we never left. You can relax. Your family won't even miss you." Percy gazed into Oliver's eyes to show him he was telling the truth, that he needn't be worried.
