"Where are you going, Lucius?" Narcissa asked.

"...Somewhere." He said, grabbing his coat from his room.

It was always the same thing- he'd leave the Common Room every Monday night, and never took her along, never told her where he was going.

"Lucius... are you cheating on me?"

He stopped in the doorway and turned slowly. "Why would you say that, Narcissa?"

"Because you always leave on Monday nights and never tell me where you're going. It just... it just seems like you're trying to hide something from me, something kind of personal like you're cheating on me or something."

Tell me I'm wrong, she prayed. Tell me it's something else.

Lucius seemed to consider this. "I... yes."

She closed her eyes. "Go."

"Narcissa-"

"Go!"

As soon as he was out the door, she grabbed her own coat and cast a Disillusionment charm, before following him. She was a Black, and Blacks curse the Other Woman when they steal their boyfriends.

Lucius finally stopped in Hogsmeade, going into an abandoned building. Of course, she followed him again.

Bellatrix, Rabastan, Rodolphus, Regulus, and a few other Slytherins were already there.

"What took you so long? The Dark Lord will be here any minute!" Bellatrix snapped.

"Give me a break, Bellatrix. I just broke up with Narcissa."

Bellatrix's wand was out in a flash. "You have five seconds to tell me why you broke up with my baby sister, and it better be a good reason."

"She asked me if I was cheating on her, and I said yes." Lucius said.

Bellatrix raised her wand. "Sectum-"

"Hold it, Bellatrix. Let's hear why Lucius said that." Rodolphus said.

"Maybe he had the sense to tell my sister the truth." Bellatrix said, though she lowered her wand.

"Did you tell her about all this? Would you try to protect her, at all costs?" Lucius snarled.

"The difference is, I don't actually try to sneak out under her nose! I walk out a few hours earlier. You try to spend every spare minute you can with her, so she's obviously going to be kind of suspicious when you just leave every Monday."

"Excuse me if I just gave up the love of my life so that she doesn't follow the path of her older sister." Lucius snapped.

Then the lights snapped off. Narcissa restrained the urge to gasp, and moved slowly back to the wall.

"My lord." Bellatrix said, curtsying while the rest bowed.

Voldemort regarded them all coolly. "I thought I told you to bring an extra member."

"My lord....?" Severus Snape spoke up.

"Another member. A Slytherin, a Pureblood. I want the cream of the crop, not Dumbledore's leavings."

Narcissa took a deep breath, and took off the charm. "H-here, my lord."

Bellatrix and Lucius stared at her, then Bellatrix glared at Lucius and mouthed the words, your fault.

"And who are you?" Voldemort asked, looking slightly interested.

"Narcissa Black."

"Slytherin?"

"Of course, my lord."

"Popular in school?"

"I guess...? I get along pretty well with the other houses...?"

"Perfect! Bellatrix, good job bringing your cousin...?"

"Sister, my lord."

"Really?  But that doesn't matter. What matters is that she's here."

"Yes my lord."

"So, have you all finished working on the spells I assigned to you?"

"Yes, my lord." They said together.

"Good. Bellatrix- teach them to your sister, and carry on the good work. I must leave immediately, my Older Death Eaters are probably poking my snake again."

With that, the Dark Lord Disapparated, and Lucius and Bellatrix started a three-way glaring contest, while the others shuffled back to the castle.

"Of all the stupid... why, Narcissa, why?" Lucius groaned.

Before Narcissa could answer, Bellatrix snapped, "I'll tell you why! Because you told her you were cheating on her, and she wanted to hex whoever you were cheating with!"

Narcissa nodded. "That's exactly why, Trixie."

"So, it's all your fault." Bellatrix said smugly to Lucius.

"My fault?!" He practically yelled.

"Never mind that! I gave him the idea to say that in the first place, and I just made sure the Dark Lord didn't curse you all into the Next Ice Age!" Narcissa snapped.

"Yes, you saved your darling boyfriend, and now I have to get you back before you freeze to death." Bellatrix said, grabbing Narcissa's arm.

"I'll get her back to the Common Room." Lucius said.

"Nope. I like having a sister, not a block of ice. You'll take your time and be all, 'I'm sorry I lied, just trying to protect you, thank you for revealing yourself at an oppurtune moment' and she'll be all, 'it's okay, I still love you' and it's annoying right now, okay? Plus, you're both going to freeze before you get done with the drama." With that, she left.

"So... should we just forget that whole thing earlier?" Narcissa asked on their way back through Hogsmeade.

"Maybe. Narcissa, I love you, and I'd never cheat on you. You know that, right?"

"Now I do."

He shot her a look. "You really thought I was cheating on you? With who? Who could I possibly cheat on you with?"

"Oh look, the Three Broomsticks is still open." Narcissa said.

Lucius sighed, and they walked in. It was the most full they'd ever seen it, but still managed to get two seats at the bar. "Answer the question, Narcissa."

"I'm considering my answer. The top three are Molly Prewett, Morticia Hale, and Fiona Baker." Narcissa said sullenly.

"Molly...? Morticia? Fiona...? Narcissa, you're perfect."

"I feel a 'but' coming on." She said.

"But what? Molly is clearly with Arthur, who I hate, and I don't even like redheads."

"Morticia's a brunette, and Fiona's a blonde."

"Morticia, to be honest, scares me, and Fiona is too much of a tomboy."

"Fine. But with you sneaking off every Monday, what was I supposed to think?" Narcissa asked.

Lucius fell silent.

"Let's just forget it and drink our butterbeer." Narcissa sighed.

"Remember what I told you when we first got together?"

"Sarcastic insults?"

"I told you I loved you. I still do, Narcissa. I always will."

"Lucius... I think half of love... is jealousy. Thinking someone you love is so great, that everyone else must want them too."

"Here are your Butterbeers." The new bartender said.

"Thanks...?" Narcissa said.

"Rosmerta." She said, blowing a lock of hair out of her face.

"Thank you, Rosmerta." They said together before she disappeared into the fray again.

"What are you saying, Narcissa?" Lucius asked, frowning slightly.

"I love you too. Always have, always will. What I'm trying to say is... forgive me?"

Lucius didn't answer. He was too busy kissing her.

Why do all Narcissa's stories end like this? Never mind, I like it.

Also, yes, the Fiona thing was a shout-out to KSA. I don't know why, I just felt like doing that.
