Rouge Lupin is Remus's twin sister. She went to Hogwarts just as Remus did, but ended up in Ravenclaw. Rouge isn't different than her brother. Rouge is energetic, has a short attention span, and is very outgoing. Rouge is the life of the party, but she can also be serious, a total genius, and a bit nerdy. Rouge is a sweet Ravenclaw. Rouge doesn't see her brother as often because of them being in different house and many don't even realize that they're twins. What happens when Rouge gets put in her brother's Potion class in 6th year. How can one Potion class change her life and the marauder life so much?
