Headcanon about if/when Mary knew Glenda became a Death Eater?
The first time she sees the mark etched into the skin of someone she cares about, Mary recoils in horror. When she sees Glenda’s mark, there is a part of her that is horrified and there is a part of her that wants to run away in the other direction but she is too tired to run. Reacting with surprise would imply there was any involved. There are few things that surprise Mary anymore.
“You don’t understand, Mary. I had no choice.”
The parallel nearly takes her off her feet. Instantly, she can feel the tears fill her eyes even as she let’s out a bitter laugh. “At this point I should just be made an honorary member,” she mutters, Glenda’s big beautiful eyes narrow in confusion. “I’ve heard it before,” Mary’s gaze evens, she pushes back the tears and clarifies further, “That excuse. I’ve heard it before.”
“You need to get out of here,” Glenda’s gaze drops though she looks as though she wants to press farther. Maybe. A mark on her arm tells Mary that maybe she doesn’t know Glenda at all. “Please. Just go home. Somewhere safe. Away from here.”
“Or what?” There is a beat of silence between the two women, Mary watches her as if she is daring her to do something. Then again, at this point it’s possible she is. “You’ll kill me like you have other mudbloods? Or will you let someone else do the honors?”
“Please,” is all Glenda says.
Mary steps forward and hugs her tightly. “You’re better than this,” she whispers, pressing a kiss into the dark hair of the woman. “You can do so much more, be so much more.”
She doesn’t allow Glenda time to prove her wrong before she disapparates.
