Oh, I really do love Severitis stories...and this was certainly a fun take on it! I loved how you mixed the magical world with the racing world and it worked so well. The Lupin appearance was a great surprise, as was Lily's sexual preferences!
The whole story worked so well, and I'm happy they came back to the Wizarding World at the end...they both deserve to be happy there and not be outsiders. Great job, fellow Snitch!
