Sirius leaves, Regulus dies, Orion dies, Walburga dies. Sirius comes back. This is the story of the Black family, one member at a time

Remus has always been the one to get the Marauders out of trouble. Sirius is so used to it, he almost expects him to burst through the crowd of Aurors and get him out of this mess. But of course, that's not what happens. Remus won't come, simply because Remus doesn't know what he's done. Remus doesn't know he's killed James, won't know until tomorrow, and it'll be too late

Regulus hates being caught off guard, so he observes people's behavior. This is how he sees Sirius, though the years.

If you were to ask them, most people who knew Bellatrix Lestrange would tell you that she was insane. Those who had met her before she was sent to Azkaban would tell you she always had been. Of course, those who knew her from childhood would tell you monsters weren't born, but created.

Bellatrix's parents make her choose to marry either Rabastan or Rodolphus. An interaction, the covered sky and two brothers are all it takes.

Sirius' thoughts while he is in Azkaban and when he escapes.

Regulus writes Sirius a letter before leaving for the cave explaining his actions and his choices.

The Whomping Willow watches as people come and go, though it does see some more often than others.

Sirius' thoughts everytime he sees Harry during POA.

Maybe Hermione was not the only one to turn Snape's essay in. Maybe Julie Black had too

Dumbledore recieved something from the future and they read it in the Great Hall
