Bellatrix had decided to take her fight to what was left of the Weasley's. the two twins partnered with their father were fighting with pure rage after suffering the loss of their matriarch and a son.  "You bitch!" cried Fred, or maybe it was George. All Bellatrix responded with was a sharp cackle and some well aimed spells. The group of them starting to take steps away from her. The pure power she was channeling suddenly waking them to the reason their family had lost its numbers. Narcissa joined in her shadow, sending spells between Her sister and Hermione, who had prioritised aiming for anyone else wanting to fight against the three of them from different angles.
