Regulus Arcturus Black(1961 â 1979) was a pure-blood wizard, born to Orion and Walburga Black, and the younger brother of Sirius Black. He was a member of the House of Black, an old wizarding family. He attended Hogwarts School of Witchcraft and Wizardry in 1972 and was sorted into the Slytherin house.
Snape was vindicated of his past crimes / acts of darkness. I think Regulus is yet another Slytherin that is not all bad, similarly to Draco Malfoy, one of his biggest downfalls seems to be the weakness he had in regards to his family, following blindly...maybe that is something left out of the Sorting Hat's rhymes.
