Legolas watched as Aragorn rushed off into the forest. Gimli was grumbling, and the hobbits looked worried. Suddenly, he heard something; voices, angry voices. They sounded like...
"Boromir," Legolas growled.
Gimli looked up.
"Stay with the hobbits, Gimli. Keep them here!"
"Wh-" The elf was gone before Gimli could ask any questions.
Aragorn had run the wrong way, he had misread the tracks, or maybe Frodo had meandered along to distract him. The angry voices rang in his ears.
"If you would but lend me the Ring-"
"No!" Frodo replied.
Legolas picked up speed, they had all been fools not to see this coming.
"Why do you recoil? I am no thief!"
"You are not yourself!"
Legolas started running.
"YOU WILL BEG FOR DEATH BEFORE THE END!"
"YOU FOOL!" Boromir shouted, his face ugly with hate. "It is not yours, save by unhappy chance! It could have been mine! It should have been mine!" The Gondorian attacked the hobbit. "GIVE IT TO ME!"
"Boromir, that's enough!" Legolas grabbed the man and hauled him off Frodo. "This is madness!"
Boromir let out a wordless howl of rage and pounced on the elf.
"Legolas!" Frodo shouted. He hesitated, then fled towards the river.
Boromir pawed at the elf, screaming senselessly. Legolas siezed Boromir's wrists. "Have you lost your senses? The Ring was not meant for us, Boromir!"
Boromir struggled, freeing a hand from Legolas's grip. He grabbled the elf by the throat, but Legolas broke free. They each wrestled to pin each other. Legolas knew he was stronger than Boromir, but he didn't want to hurt him. He planted his feet in Boromir's stomach, but the stubborn Gondorian clung to the Mirkwood elf's tunic. He got a hand on Legolas's throat again and drove his knee into the elf's abdomen at the same time. The air rushed out of Legolas.
Boromir, a mad light shining in his eyes, siezed one of Legolas's arrows from where it had fallen from his quiver.
"Boromir, please," Legolas choked. The elf twisted his body-the arrow went into his side rather than his heart.
Aragorn followed the hobbit's tracks right back to the river. The hobbits were grouped around Frodo.
"Where did you go?" Aragorn asked.
"Boromir...Legolas-Boromir attacked Legolas," Frodo said breathlessly, winded.
"What? Why? Where?"
"Boromir tried to take the Ring, up the hill...at some ruins. Legolas...tried to stop him."
"Everyone, into the boats. I'd rather risk orcs than what I can feel coming. Gimli, get them moving."
"But-Aragorn!" Gimli spluttered.
"Do it, Gimli!" Aragorn called over his shoulder.
