Bellatrix watched as her sister was thrown from the manor. She couldn't believe her own sister. Her own flesh and blood. Could betray her like that. They were sisters. They were best friends. She was her sanity. But now as Bellatrix watched her Andy. No! Andromeda walk away her very heart hurt. That had never happened before. She hurt terribly as the realization hit her that her sister had chosen a mudblood over her own family. She had chosen a filthy mudblood over Bella. Bellatrix glared after the retreating form as her bedroom door opened. The intruder walked behind her. "She's gone Bella. Andy is really gone." Her baby sister sniffles. Bellatrix sneered. "There is no Andy only the bloodtraitor." She hissed. They could and would never be Bella, Andy, and Cissy. There was only Bella and Cissy. And Bella's heart would never allow another to enter it. She would never allow her heart to break again. Not after Andy.
