Disclaimer: I do not own The Hobbit
It took a long time for Bilbo to stop flinching so violently when other people touched him. It also took a long time for things to return to normal and Bilbo woke up years later still plagued by the occasional nightmare. Things were never quite the same but with Kili and Fili and especially Thorin, not to mention the rest of the company, Bilbo recovered. He was also quite pleased to see Thorin end the pale orc's life. Thorin became king, and Bilbo was his consort, loved by all. Fili and Kili lived with them in the castle under the mountain and helped rule with love, understanding and patience.
