In the book Hoot by Carl Hiaasen, do Roy's parents decide to adopt Beatrice? What type of career does Roy go into after he graduates? What happens...

These are all questions that are not answered in the book, even in the Epilogue. To answer these questions, you must speculate about what you think could happen to these characters if the story went on. This is an interesting way to engage with a novel and a way of testing your reading comprehension. There are no right or wrong answers to such questions, but you should base your opinions on things that happened in the story or on your understanding of the characters.

So, do you think Roy's parents would end up adopting Beatrice? This seems plausible because we know Roy's mother miscarried a baby girl and was devastated by that. She is profoundly saddened when she finds out Mullet Fingers's mother doesn't want him. On the other hand, Beatrice is very loyal to her father and feels responsible for him. It seems unlikely that she would leave him. One might imagine a scenario where Mrs. Eberhardt unofficially adopts Beatrice and becomes a mentor to her, so Roy's mother would have some experience of having a daughter and Beatrice would have a positive female role model in her life.

What career might Roy decide to pursue? He loves the outdoors, so one might envision him becoming a naturalist or working for Everglades National Park. Roy is also concerned about people, as we can see in the way he befriends Mullet Fingers and Beatrice. Having seen the less-than-optimal performances of the guidance counselor and vice principal at Trace Middle, he might decide to become a school administrator who really cares for kids and works for their best interests. Since Roy has an inquiring mind and a desire to see justice done, one can also see him following in his father's footsteps to work as a law enforcement agent for the Department of Justice.

The Epilogue reveals that Lonna, Mullet Fingers's mother, is having relationship difficulties not only with her son and step-daughter, but also with her husband. One could imagine that Leon Leep divorces her after he sees her more clearly for who she is when she falsely accuses her son of stealing. Perhaps the crisis in their marriage leads both Mr. and Mrs. Leep into marital counseling, and Leon gets help for his alcoholism and depression. Through counseling, they might see how they have failed their children, and they may move toward a more functional family environment.

You can choose whatever outcome you prefer for the characters once the book has ended. That helps to make a story even more satisfying.
