"Given an 2^n by 2^n chessboard, with one corner removed, show that you can cover it completely without overlapping or going off the board using only triominoes of the above shape… What was the 'n' standing for again?" Scootaloo said quietly to herself as she was chewing on her pencil. "Something with variables that-" Before she could finished her sentence the door swung open and another pegasus, a mare with a white coat entered the room, her expression showed that she was annoyed, her purple/lightblue mane was messed up as if she had been outside in a storm, but the weather was fine. Scootaloo looked up to her mother. "Were you having a fight again?"

After a fight between her mother and her stepfather the pegasus filly Scootaloo goes outside, in the middle of the night to get her mind off everything that happened, she doesn't care that she is entering the dark Everfree Forest. She just needs some time alone. But she isn't alone, something, or somepony is following her, a black-coated filly who wants to be her friend, who wants to help her to fix all of her problems inside Scootaloos family. And she will but the way she is going to do it will probably not be the way Scootaloo wants it to be done.
