(ii) Teddy Lupin: A Gryffindor who decides to remain lost, until a particular red-headed Slytherin makes it her sole mission to find him. (iii) Justification: All because she's an obstinate (determined) girl who has an epiphany that the destination of her confusing journey is a blue haired boy (man).
