For a prompt on tumblr (Lucissa, "Everything's going to be fine" and "Stop trying to cheer me up!")

.

Narcissa sat in bed early that night, clutching a small slip of parchment in her hand.

"Cissa, are you alright?" Lucius asked after a while, having opened the door so quietly she didn't know he'd come in the room.

She didn't respond, but crumpled the letter in her fist before looking at him.

"What's wrong?"

"Wrong?" she scoffed. Narcissa took a deep breath. "Andromeda's gone. From Bella," she murmured, opening her hand to show him the ball of parchment. "It's not surprising, really. We've all expected it for ages, I just never truly thought she'd leave.

"Apparently she's with that Tonks now," Narcissa spat. "I can hardly believe it."

Lucius looked as though he was carefully calculating his every word. "Her loss, then, if she's distancing herself from you. Surely you'd be better off without her…"

"She's - she was - my sister."

"Everything is going to be fine—"

"You can't know that," She retorted. "She's disgraced the family, Mother and Father'll be furious, I expect." A pause, then: "I may never see her again, Lucius. My own sister."

"If she would prefer the company of a Mudblood to you, she's no great loss—"

"No! Stop trying to cheer me up, you're not helping matters." She looked away from him, back to the letter in her palm. "I'm going to see Bella, I might not return tonight."

"Narcissa—"

"I just need some time to clear my head. I'll be home tomorrow."
