I am guilty of giving Remus a younger sister. In my defense, she was born Pre-bite, and died at a young age.

My story (not archived anywhere)revolved around the bite, and becoming a werewolf.

Remus (age 9) and his sister (Roma, age 5) were playing outside when they were attacked. Remus was bitten trying to save Roma (Who died later of her injuries anyway).

Remus's parents did all they could to try to help the child they had left. It was very angsty, perhaps a bit too angsty, so I don't plan on putting it up anywhere.
