Amon Hen

"So…" the Ringbearer said softly. "You've come to try to take the Ring."

Boromir began to speak but the Ringbearer cut him off. "Save your excuses.
You wanted the Ring from the moment you first saw it. I always knew that it
was only a matter of time."

"Gondor must have it." Boromir said firmly

"It's not going to Gondor and you're not going to touch it. I'll kill you first."

The steely glint in the Hobbit's eyes unnerved Boromir for a second but then his resolve hardened.
He was the Captain General of Gondor. A warrior born. No Hobbit could possibly be a match for him.

He stepped closer. "Do not struggle, Ringbearer. This is for the best."

In one smooth motion the Hobbit drew Sting. "I am the Ringbearer. And you are a fool."
