They're still trying to hurt the survivors, as much as they can. This may have been a mistake, but there's no going back now.

When they arrive, he turns to her - silver in eyes and hair, but still recognizable as her brother - and gives her a big hug that would be more comforting if he wasn't so cold. Room temperature, really. "I'm so sorry, Cass."
