Scootaloo doesn't know how and/or why she is at a random, unknown, and almost deserted island. As much as she wants these questions answered, she will find out "what" she will do about it and "who" she will meet there. Despite the confusion, at least she is not alone on this island. At first she wanted to stay on the island for a day; however, maybe she wouldn't mind staying here forever.
