Ashley was wide-eyed and red whilst Tom was exasperated and embarrassed. Both reactions were caused by the sight they witnessed in one corner of the room. Apparently, all Moko needed in order to feel better was the presence of a fellow serpent because he and Nagini were right there, mating. The...occurrence was something neither of the Hogwarts Heirs had ever wanted to see at any point of their lives. They were happy and proud that their familiars found a mate in each other but doing the deed in public was just so unnecessary and, at the very least, inappropriate. But, well, they were literal animals so they couldn’t really be blamed for that. Tom later explained that Moko’s unknown weakness was indeed caused by not having his mate with him during the current mating season.
