In the clearing above Woodhall a fire flickers bright and warm. The Dwarves declared they would turn in early, and the Elves did not press them; but Bilbo sits long into the night among the Firstborn, enjoying food and wine and song.
"Do I, immortal, imagine it," Laeglith asks softly when at last the Hobbit is snoring in his bed-roll, "or does our little friend still never seem to age?"
Gildor frowns in thought. "So, I'm told, they say in the Shire. But... I have a feeling, whence I know not, that Bilbo may have been living on borrowed time."
[Gildor Inglorion tells Frodo in the woods above Woodhall in FoTR Book I Chapter 3, Three is Company, that he has seen Bilbo twice since the Hobbit left Bag End; "He said farewell to us on this very spot."]
