Hers

Insanity

Elise sat near Sesa's window, watching his every move.

It hadnt been hard, following him.
Just listen for the sports car engine.
Then sneak into his room when he wasnt looking.

Way to easy.
As he snored on, she sat in his chair beside his bed, holding a butcher knife as his brother slyly opened his door, sneaking in and ruffling through his things.

"Thats not very nice, Aito." She says, smiling as his brother nearly shit himself.
"Hey! Who're you and whatre you doing here?!" He demands, not seeing the knife.
Elise stands up, insanity seeping through her voice as she states, "His one and only."
Aito was terrorfied.
"Are you insane? This is breaking and entering!" He countered, slyly grabbing his brothers fire crackers.

"I am. But so what? Soon, we'll have this amazing house to ourselves. But first, you die!" She says, charging him and causing him to stumble out of the room and fall down the stairs.

She smiled as he lay there, neck broken and unable to move or speak. "Next up, Mom and Dad." She says, checking the rooms and finding them dead asleep.
"Too easy..." she huffs, "Not much fun to be had here, but oh well." She raises the knife, then stops because she had a better idea.

Amonia and bleach plus...
She smiled again, sneaking intk the bathroom and grabbing the chemicals she needed, laughing silently to herself.
"He is mine. No one elses. If he thinks differently, Ill make him see my way." She says as she turns on the stove, laying out the materials to make a deadly poison.
