The twins played with their dolls, at first sight seeming happy and innocent and carefree. But if you look closely, you'll notice a tension in the air, a storm lurking around the corner, a disaster waiting to happen.

Then… snap. One of the girls grabbed the other's doll, pulling at it fiercely in an effort to make it hers. The other stared angrily, blue eyes blazing as she held onto the toy, showing no sign of giving it to her sister.

The struggle intensified over the next few minutes, when suddenly the motor of a car was heard just outside the house, becoming louder and louder until it stopped completely.

The first twin suddenly loosened her grip on the doll, while the biggest, meanest smirk crossed her face. Suspiciously, her sister watched as the little girl jumped up from her chair and made her way towards the kitchen counter, reaching up to grab one of those big, forbidden knives that Mommy and Daddy always tell her to stay away from.

Meanwhile, the other girl has stood up as well. More cautious, as if she were afraid for her own safety, she moved slightly backwards, flinching as her armed sister took a step towards her with the weapon.

When they heard the rattling of keys and the click of the opening door, the twin with the knife attacked.

Just not the way anyone would expect her to.

The blonde plunged the blade into her own shoulder, letting go of the handle and letting out the most miserable, pitiful wail you've ever heard.

Immediately, the parents came rushing in, followed by an older boy.

"Alison!" The mother shrieked as she set her eyes on her injured child. "Omigod, what happened? Kenneth, quick, call an ambulance!"

As her husband dialed, he sent a look that could kill to his other daughter. "Courtney? What have you done?"

By the end of the day, the guilty twin lay in a bed with stuffed pillows and buckets of ice cream, the innocent one behind bars surrounded by doctors and medical tests.

"We're moving to Rosewood," Kenneth declared the next day.

His family, consisting of a wife, one son, and one daughter, did not argue.
