"Fíli! Fíli!" Kíli found himself calling out frantically for his brother as cold tears ran down his cheeks. He could not see Fíli anywhere, just still bodies scattered around him. His voice was weak and hoarse, and he wondered if he was even making any noise at all.
"Fíli!" he cried out desperately, trying to hoist himself upwards but the pain surging through his body was unbearable. "Fíli, please, oh Fíli…"
"Kíli," croaked a familiar voice from beside him, and he saw his older brother from out of the corner of his eye and all of the pain seemed to vanish for a moment, "My brother, I'm so sorry. I-I should have protected you."
"We were protecting Uncle Thorin, Fee," Kíli wept, "That was the honourable thing to do, was it not?"
"Yes, nadadith," said Fíli, "And we'll be remembered as heroes." He took hold of Kíli's hand as firmly as he could, though his energy had almost run out, "Our mother would be so proud of you, Kee."
Kíli let out a loud sob at the mention of their mother. "Oh Fíli, I promised her! I promised I'd come home!"
"Hush, do not worry about that now. I'm here, it'll be alright."
"Fíli, I'm so scared," the younger dwarf whispered, looking at his brother with eyes glazed with tears, "I didn't think… I didn't think it would end like this."
"I know, brother, I know," Fíli began to cry also, heartbroken, "But at least we are together."
"Yes, together," said Kíli. He managed to smile weakly, and Fíli smiled back lovingly, "But it would have been nice to see inside the mountain, just once. Those stories Uncle told us… I always dreamt of being here at Erebor, the greatest kingdom there ever was… And here we are, but this isn't how I imagined it."
"I know," said Fíli, and he meant it. For years he had longed to see the Lonely Mountain in all of its splendour, and yet now, after the terrible battle, it didn't seem so great after all. "Kíli… Kíli?"
His attention went back to his brother and he noticed with horror that Kíli was no longer moving, no longer blinking, no longer breathing… And he was no longer Fíli's little brother. Just a lifeless corpse, cold and still and silent.
"Mahal, no…" Fíli sobbed, and he found the energy to take Kíli in his arms and embrace him. "Oh, my Kee, my little Kíli... No... Kíli, no..."
He cried into his brother's dark hair, and let out one last yell of rage and despair before darkness took him.
