Is it really that big of a shock though? Cassiopeia Black, that's right, younger sister of Sirius, she's been quite shielded from the world and is stuck in the muggle world hence her overprotective father. But what will happen when she formally meets the marauders? "But what if I hurt her" "You brought out the badass in a careless mans careful daughter, trust me when I say your the best thing that could've ever happened to her James Potter." James Potter x OC.
