A/N: This one is based on Mad Hatter by Melanie Martinez. It's a clean song but with a disturbing topic, so a quick warning on that.

"Do you think she'll be all right?" Narcissa asked.

She and her older sister, Andromeda, were sitting at the window of their house, waiting for Bellatrix to return.

"She will. You know her. She wouldn't show any cowardness in front of someone like You-Know-Who. You've seen how ambitious she was while practicing. I've never seen someone do so many Unforgivable curses,"

"She was scary. Like she was actually crazy. She killed anything she saw during that walk in the woods,"

"She Curciated them first,"

"There she is!" Narcissa pointed out the window, where Bellatrix had just Apparated. "She looks all right, d'you think she has the Dark Mark?"

"I dunno," Andromeda said, following her sister out.

"Bella! Bella! What happened? What did he say? Did he give you the mark?"

"Quiet, please," Bellatrix sat down on the magenta armchair. "He put me through some sort of tests. Made me duel some of the other Death Eaters,"

"Duel them?" Narcissa said anxiously.

"The Dark Lord ordered them to not use the Killing Curse. But they used the Cruciatus Curse quite a bit, but I dodged most of them,"

"Most?"

"I was resistant to the ones I took. I wanted to prove that I wasn't like the others. That I'm mad. I resisted myself as best as I could to those,"

"How did you resist?" squeaked Andromeda. "I could hardly take half the Cruciatus Curse,"

"I just tried to think about what would happen. I, being the Dark Lord's most loyal servant. I, fighting alongside him. It was surprisingly easy," She rolled up her sleeve, and revealed the dark mark, with the interlocking skull and snake.

"Ho-ly… You got that?" Narcissa breathed. Her mouth was open wide enough for a bird to make a nest in.
"I told him that I had two younger sisters, he said he'd be glad to have them as a 'part of the group' someday. Andromeda, you just graduated Hogwarts. As far as the Ministry knows, you're a saint. The last person they'd assume to become a Death Eater,"

Maybe I am a saint, Andromeda thought, but she stayed quiet.

"Just think, Andy! Bellatrix and Andromeda, the sisters of Black, the Death Eater Duo, the Dark Lord's most loyal servants!"

Andromeda nodded, staring at the carpet.

The next few weeks were full of discipline. Bellatrix spent every second of her downtime teaching Andromeda how to use the Killing and Cruciatus Curse.

Bellatrix had shown her to Kill nature. Any animals that wandered into Bellatrix's line of vision came to a terrible fate.

"Enough!" Andromeda yelled. "You're completely psychotic,"

"That's the nice way to put it," Bellatrix twirled her walnut wand around in her fingers. "I'll tell you a secret. Everyone's crazy. All the best people are," A squirrel came and Bellatrix Cruciated it and it dashed away in fear the moment she lifted it. "You're crazy, too, Andromeda,"

"What?"

"I know you're off your rocker as well," Bellatrix turned away from her sister. "It's probably the reason that we get along,"
