Harry restrained from letting out a laugh when he advanced on his prey and saw fear in her eyes. Bellatrix Lastrange was trapped like the rat she was, after moths of searching and following the wench she was here and about to be captured. She fell backwards against the brick wall, dodging every spell thrown at her. Harry stopped and watched her for a moment and suddenly fear gripped his heart, what would a happen? Harry never stopped to consider the consequences of what a mad woman would do when trapped. He lifted his hand and motioned for his comrades to cease-fire. His wand at the ready he approached her slowly, ready to subdue her and take her into custody.
"Baby Potter" Bellatrix said, malice dripping with every word, "You are so amusing"
"I am sure" Harry replied, "But what's even more amusing is your position currently. No where to go Bella, no where left to run"
Bellatrix did something then that surprised Harry, she smiled, and her cruel smile that made Harry want to wretch. "You are so noble baby Potter," She continued, "I wonder how you would feel if you knew?"
"Knew what?" Harry spat, part of his brain was telling him just to get on with it, that nothing good could come from what she was about to tell him, but there was another part that forced him to steady his hand and listen.
"Ask them" Bellatrix rasped, "Ask them about your sister. Tell them she's alive and closer than they think. Ask them"
"What are you talking about?" Harry growled. Bellatrix laughed and before Harry knew what was happening she lifted her wand and brought it level to her chest. The words were hissed low and only Harry heard the curse, "Avada Kedavra"
"No" Harry bellowed as she slipped down the wall and her limp body hit the ground with a smack. He hit his knees in front of her. Now she couldn't tell him about horcruxes, now she couldn't tell him where Voldemort was and now she couldn't explain her suicidal confession.
