Here is my response to Lady Eleanor Boleyn's Decisions challenge on The Dark Lord's Most Faithful Forum. My prompt was "killed".
It was just another ordinary day in the life of Bellatrix Black. In the morning, she noticed that her mother was very anxious about something. At twelve o'clock, Rodolphus Lestrange arrived at her house.
"Hello!"
"Hello, Bella! I need to speak with your father. Where can I find him?" Rodolphus asked.
"He is in the library," was her reply.
Rodolphus went to the library, and after thirty minutes he returned in the dining room with a large smile on his face.
"Bella, would you care to show me the gardens? I think I saw a beautiful rose which I would like to pick for my mother," asked Rodolphus.
"Well… uh…" Bellatrix started to say.
"She'd love to," her mother said quickly, cutting her daughter off.
"Shall we?" Rodolphus asked, as he led the way.
They walked in silence and they arrived in front of a beautiful rose.
"Bella?" he asked, anxious.
"Yeah," she replied with boredom.
"Er… I just wanted to ask you something important: will you do me the honour of becoming my wife?" Rodolphus went down on one knee and held out a box.
Bellatrix was speechless. In her head an odd process was happening: voices were battling in her head.
Yes, say yes! Accept his proposal!
Why should I? I don't even love him!
So what? Love is a bonus in a marriage! Love doesn't matter!
Okay, I understand that. But why I should marry him? Just to please my parents?
Bella, it is your duty to marry and to produce a male heir! You don't want to disappoint your parents, do you?
No, but… I really don't want to marry him! Marriage is disgusting!
Bella, you know very well that remaining single is a disgrace, you don't want to be called an old maid! You don't want to end up like your great-aunt, Cassiopeia!
It's so hard to make an important decision!
Rodolphus is staring at you! He is waiting for an answer, and you'd better give him the one he wants to hear!
I still don't want to marry him! A husband is what's left of a sweetheart after the nerve has been killed!
Oh, you're so deep!
Don't you dare use sarcasm with me! You are just a voice inside my head!
Just accept his proposal and I will leave you alone! Rodolphus is a Death Eater, he can introduce you to the Dark Lord.
You are right! I will marry Rodolphus so I can become a Death Eater!
Finally!
"Yes, I will marry you!" Bellatrix said.
Rodolphus seemed to be surprised, for a long time he had thought that she would refuse him.
"I promise you that I will be a faithful and loving husband! I love you, Bella!" he said with happiness.
His delight was annoying, but she faked a smile.
"I love you too, Rodolphus!"
She made a promise to herself that she would never regret her marriage with Rodolphus. Becoming a Death Eater was the only reward she wanted.
