Inspired by the following Shirebunny: Did Bilbo know that Sam was memorizing his poems? The verses in the drabble come, of course, from the chapter 'A Knife in the Dark'.
Gil-Gil-galad was an Elven-king.
Of him the har-harpers sadly sing.
The familiar stanzas, hesitantly recited in a sweet childish treble at odds with their lofty subject, floated into the study from the garden.
the count-countless stars of heaven’s fie-field
were mir-mirrored in his sil-silver shield.
Remarkable, Bilbo thought. Sam’s zeal and determination were really quite remarkable in a child his age. “I wonder if I am doing the lad a disservice,” he said aloud.
“Nonsense,” said Gandalf. “You’re giving him wings to fly, Bilbo.”
To where? Bilbo wondered.
for into dark-darkness fell his star
in Mor-Mordor where the shadows are.
