In another part of town, Tammy, a waitress at small local diner with big plans for the future, looks out her window and is excited to see a shooting star, which she takes as a good sign for her dreams. Suddenly "something shoots overhead and crashes" in the nearby mountains. Assuming it is a fallen meteorite, Ted wants to investigate in person.

While she remains on Earth, she finally leaves the small town to go in search of her own destiny.  answer the following question:  What is the profession of the person who helps Urp?
