*sighs* I'm a little disappointed. Oh well. A few of the questions I wasn't sure how to answer. That was the first time I did that though... *sighs again*
My brother joined a Local Muggle Quidditch team. It's actually kind of funny watching him run around in a green cape and and a broomstick between his legs.
Snape, Slughorn, Tonks, and Regulus Black were all Slytherins. Also, Narcissa Malfoy saved Harry's life by lying to Voldemort.
Hell, Pettigrew a.k.a. Wormtail was a Gryffindor and he was evil and cowardly. TDF is right. Tonks was a Hufflepuff.
You're right. I got Tonks mixed up with her mother Andromeda, a Slytherin who was disowned by the Black family for marrying a Muggle-born.
