Harry apparates Dudley near the Leaky Cauldron, and therefore doesn't get sent a warning. Also, he doesn't go to Grimmauld Place. He also doesn't end up in front of the Wizengamot either for casting a Patronus Charm to save his and Dudley's life. However, he does find another mystery. Grey Harry.
Dottie was missing her friend. He normally had sent her a letter at least by the fall. She doesn't know that a werewolf that heard her talking about it has the answers that she was looking for.
Reuben didn't know his coworker was a werewolf until he bit him. However, because of the death of his other pack member he needs another one in a couple of years time. The problem? He does not get much social interaction with people his age, and the girl he is attracted to is slightly oblivious.
A quiet romantic plot.
