Upon hearing Violet say 'I'm... Finally free...' Finn had a flash back...
A young Finn was in a science lab, he was holding a girl's hands. The girl had light brown hair.
"Never forget me! I'm... finally free..." The girl said, cheerfully.
Finn nodded. The girl entered the portal in the room. A beam of light was shot out of the portal and disappeared. Finn's adoptive father, Joshua came in and hugged Finn.
Finn's flash back ended. He broke the ice cage and set Violet free. Violet grew wings and flew out carefully, trying not to touch any part of the treehouse. Finn wanted to shake hands with Violet but she avoided contact with Finn.
"Sorry, no touching..." She said softly.
She grabbed a stray piece of wood on the ground. The wood wilted in a few seconds. Jake was horrified. Violet flew out of the window and away. That night, Finn couldn't sleep as if he needed to know something.
