They were late arriving at the train station, in a magically-expanded car that held four Weasley children, five young houseguests, one very patient Remus, and Arthur, Sirius following behind on his motorbike.

Shouldn't there be five Weasley kids in the car? Percey, Fred, George, Ron, and Ginny.

I must say that I'm really enjoying the Saving Harry universe. I've always liked Slytherin!Harry, but I never imagined Draco being in Hufflepuff before, although you managed to make it very believable. I applaud you for the magnificent job you've done with these fics. Keep up the good work!
