Legolas: I can not go back.
Thranduil: Where will you go?
Legolas: I do not know.
Thranduil: Go to the North. There is a member of the Dunedain you should meet and stay with. His father was a good man, I have hope he will be a great one.
Legolas: What is his name?
Thranduil: He is known as Strider. His true name, you must discover for yourself.
Kili: I will not hide, when others fight our battles for us!
Thranduil: So this is the Halfling who ate my food, and stole keys from my guard.
Bilbo Baggins: Yes. Sorry about that.
Thorin Oakenshield: Farewell, Master Burglar. Go back to your books, your fireplace. Plant your trees, watch them grow. If more of us valued home above gold, it would be a merrier world.
Bilbo Baggins: One day I'll remember. Remember everything that happened: the good, the bad, those who survived... And those that did not.
Answer: In both the novel and the movie, Alfrid's (who is not named in the book) fate is unknown. Beorn, in the book, stopped his reclusiveness and became a leader of the local woodmen and protected the area from orcs and goblins. He died sometime before the War of the Ring and was succeeded by his son Grimbeorn.
