a long time ago i saw a post asking why didn’t sirius take veritaserum when he was sent to azkaban and honestly i think i know why. taking veritaserum means he would have to tell that peter was an animagus, and that certainly would raise some questions such how and why, resulting on him exposing remus as a werewolf, so maybe (most certeinly) sirius orion black was sent to a lifetime in the worst place of the world because he refused to betray his best friend, the only one he had left and if that doesn’t make you cry i don’t know what will
also, he didn’t even know peter was still alive until the picture of the weasleys with ron holding scabbers was in the newspaper
