SIRIUS BLACK WAS IN AZKABAN FOR TWELVE YEARS FOR A CRIME HE DIDN'T COMIT AND HE ACTUALLY FELT LIKE HE BELONGED THERE BECAUSE HE BLAMED HIMSELF FOR THE DEATH OF HIS BEST FRIEND AND HIS WIFE AND IT'S NOT OKAY IT WILL NEVER BE OKAY.
“Even on the bus, Selena often sat in the back with her mother. Marcella and Selena could sit on the sofa back there and talk for hours. Sometimes Selena would lie with her head on her mom’s lap, while Marcella played with Selena’s hair or massaged her scalp. I’d walk back there sometimes and Selena would have this glazed look, like a cat. She was always Marcella’s beloved baby girl.” - Chris Perez [To Selena, With Love]
