Marlene: pounced on (quite literally!) by the Dark Army along with Lily, Agnes, and Abe when they'd barely first arrived. Tabby mauled her back pretty badly and scratched up her stomach and left arm some and was going in for the kill when Lily saved Marlene's arse just in time for Marly to be attacked by Fenrir! She didn't fair any better against him as he caused her to lose her wand almost immediately, and injuries there included getting her face smashed into the ground (i.e. broken nose), scratchmarks on her neck, shoulder, and chest, a major concussion from having her head slammed into twice, and had the spot where she'd been bit on the shoulder by Tabby back in July re-chomped on. She managed (somehow) to get away from that, just in time to try (and fail) to set Rodolphus on fire. He crucioed her once himself and slammed her around for a while before using her as a human shield when Dorcas tried to crucio him. And then they got to the Healers, and Hestia took her back to her place to help her stop dying, and then back to GH once she was sure Marlene wasn't going to bleed to death.

Corbina had a much better time of things, although she would argue differently. After an annoyed walk through a tunnel that was much too short for her, Corbina tried to sneak off to go fight. Demetrius tried (and failed) to stop her, and Corbina ended up duelling against Dedalus, who thought he could save her from her vile path of sin through words. This was untrue, and she kicked poor Deddums's bum a little bit. She didn't go away empty handed though, as Dedalus began to fight back, leaving Corbina with a few bumps and bruises and a slash across one of her boobs.
