Time to pay my respects to my favorite HP pairing with my favorite witch!
Lord Voldemort screamed in fury as he felt yet another horcrux be destroyed. Now only Nagini was left, and though she was safe the thought of his immortality slipping nearly troubled him. At the very least, he found it disturbing. He paced back and forth, debating what to do. He heard someone apparating nearby, and turned to see Bellatrix Lestrange.
The saucy escaped prisoner walked toward the Dark Lord before stopping. "What angers you, my lord?"
Voldemort suddenly had an idea. "Potter. We must move forward with our plan."
Bellatrix smiled. "Yes, my lord. May I kill him? Slowly, painfully, so he won't even remember who he is-"
"Your bloodlust is refreshing, but no. I must be the one to kill Harry Potter. There is, however, another task which you must complete. You alone are suitable."
Bellatrix glowed with pride at the compliment and nodded. "Anything, my lord."
"Our trap for Harry will work, of that I have no doubts. However, there is something unsettling about the planned events that prompts me to prepare a contingency plan."
Bellatrix smiled as he described the plan, and how it must be secret. She nodded her understanding. "When shall this be done, my lord?"
"Mere hours before Harry walks into our trap for a hero. There is a shack where it shall be done, and only you are to know of the deed."
"Yes, my lord. With honor, and pleasure." Bellatrix bowed and backed away before disapparating.
Voldemort sneered. Harry Potter, the boy who lived. You will come to die, and by your death my immortality is sealed.
