Disclaimer: I do not own The Hobbit
The adventure continued as the perils mounted and through it all Kili and Fili never once asked what made Thorin's home. For they knew that what he kept closest to his heard was a burning passion for one particular hobbit. And that hobbit, they knew, had an equal love for that dwarf. But true to their word, they did not speak of it again, tease or mention at all, save for late night talks with Bilbo. And as the journey ran to its end Bilbo found his place in the battle to be beside Thorin, betrayal or blind loyalty, he would stand by Thorin to the end. And to the end he did stay, and as Thorin lay there, growing cold in Bilbo's arms he smiled his last smile. And his rough hand touched Bilbo's cheek. "Home, my dear Bilbo, is where the hobbit is." He said as he breathed his last.
