This pessimistic wolf has become a strong scout to make sure his worst fears don't come true for him or the rest of the pack. He patrols to protect, looking for threats that may affect his friends.
Sirius trained hard since he was a teenager to reach this position, and even so he was impressed that he managed to be chosen. His mother Paz always supported him despite her son's insecurities and when she found out he made it she threw a huge party to celebrate.
Mother and son have always been very close, however Sirius doesn't remember much about his father who died when he was very young.
