Bellatrix sneered as Andy countered her, pointing out that the woods had been her place first. What did it matter that the woods weren't on Black land? They had always taken what they wanted, no matter if it belonged to them, and would stake claim to anything that they felt was theirs. It might have been Andy's once, but it wasn't any longer.
Mercury symbolised their connection. With him dead, the connection was gone, but Bella didn't dissuade Andy of the notion that she might go the same way as her owl.
"Was it worth it, Andromeda?"
Andy strode forward when many would have turned tail and run, but Bellatrix remained motionless, like a coiled snake ready to strike as they were showered in splintered wood and tattered bits of foliage.
Inside, Bellatrix was torn up. There was a hole there where Andy had once been. Not in her heart, the one people joked that she did not have. No, it was in her soul, Andy had been as much a part of her as the scar Bella had put on her foot when they were children.
The violence of the blasting hex didn't make Bella bat an eyelid, she had always been drawn to powerful and chaotic destruction. Nor did the mention of marked flesh have any affect. But then Andy called her sister, and Bella snapped.
"Sister?! No sister of mine would forsake her family to go to bed with a filthy mudblood!" she snarled, teeth bared as her temper flared to life.
