A smile ignites in her eyes as green flashes across the damp room.

She hears her own voice screech the words feared most.

Though they don't seem to belong to her.

Bellatrix watches as her cousin keels over, the light fading from his eyes.

Her face contorts into a grin.

Adrenaline and excitement shoot through her veins.

This is what she lives off of- Madness. Insanity. Ruthlessness. No mercy. And Revenge.

And then there's the boy.

He chokes and shouts, his voice merging with the sounds of battle.

And then he surges forward to Bellatrix with horror in his eyes.

Bellatrix breathes in fresh air and runs, playing with the boy, daring him to chase her.

{And he does- what a fool}

She cackles with eagerness.

At the top of her lungs, she shrieks, telling the entire world what she's done.

She's killed Sirius Black
