Arianna Dumbledore
Ari has spent her time between her room and the kitchen, bringing tea to the research team, and generally worrying about people. When it is safe to leave the castle again, she will find Gilderoy and hug him so long it will become improper, and she will not care.
She was not directly part of the fighting this time, but she is affected. People she knows will die, and she will throw herself into her flowers, as per usual, and try to think of hope.
