Disclaimer: I'm not J.K. Rowling. I'm just having some fun.
Why?: During Order of the Phoenix, which makes Vera 20 and Coralie 18
"Why, Vera?" Vera Black's oldest cousin, Coralie Black, pleaded.
Vera felt her heart break a little. She didn't respond right away, having no idea where to start.
"God dammit, Vera! Why are you doing this?!" Coralie yelled.
"Because," Vera started to say, her Slytherin mask wavering. "I want to make sure that our kids will grow up in a world without Voldemort. I want them to live in a world where they don't have to worry about who is the next target."
"But, Vera, it's practically suicide!" Coralie sputtered.
Vera laughed bitterly.
"I guess it runs in the family then. My parents both knew the risks of being together- they both knew they would probably end up getting killed- yet, they still risked everything," Vera stated.
"But, Vera-"
"I know the risks, Cora. I know that I will probably die. But I don't care," Vera stated firmly.
The two cousins remained silent.
"So there's no way that I can persuade you out of this," Coralie said dejectedly.
"Absolutely none," Vera stated, as she walked towards the door.
She paused at the door and turned back. "Always remember I'm doing this for you, Arlena, Jaime, and the Order. Always remember that I love you all to death," she said quietly.
After the door had closed shut, Coralie broke into uncontrollable sobs.
A/N: So, this is the motives as to why Vera goes to 'the dark side'. Introducing Coralie Black, the oldest daughter of Sirius Black & Elaine Thomson. You will see Cora in an upcoming drabble shortly, which involves her love interest, Oliver Wood. :D Briefly mentioned, Arlena and James Black, are twins and are 3 years younger than Coralie. Feedback is always appreciated. :)
