RegulusBlack3

You belong to the Blacks, Sirius and Regulus are your older brothers. Everyone knows that your brother Sirius had problems with your parents and their beliefs, as well as not being a Slytherin like the Blacks usually are.

Even though you both loved each other, you had a deeper relationship with Regulus. You noticed him acting strange lately and you learned from his trusted elf that he wanted to redeem himself, he didn't want to be on the dark side anymore. So you went to Sirius to help you get Regulus out of wherever he was.

But he didn't take it seriously, he said that Reg would never change. Even so, you took him with you by force, right where Reg was already fighting against the inferi but he couldn't, there were many until he saw both of you but he was happier to see you and he stretched out his hand asking for your help...
