Infinity

Stuck in a science lab, since her death.
She cant help it, she is rear.
But it wasn't that way in her child hood.
Now she is dead, and her family thinks she went mad.
She is different, but why didn't they discover that before?
Her vengeance is simple.
But her road to the vengeance is harder than what she expects it would be.
Is she normal?
No.
But she can act like one.
