Thorin and Bilbo

Frodo is the son to Thorin Oakenshield and Bilbo Baggins. Bilbo returned to the shire almost twenty five years ago to the day and when he left he believed Thorin and Thorin's two nephews - Fili and Kili to be dead, now however as his son Frodo is about to celebrate his twenty fifth birthday the Dwarven party returns to the Shire to check on Bilbo as he hasnt spoken to them in the years thats passed. How will Thorin react? *i did my best with the Voice*
