[Keeper of Dol Guldur]

Boromir would return five days after Aragorn got back from seeing Frodo off and would discover that not only was Faramir the Steward, and Denethor had died, but Faramir had gotten married to Eowyn.

A year before, when Boromir had ridden through Rohan on his way to Rivendell, he and Eowyn had a torrid love affair, and he promised he'd marry her.

Faramir had taken everything from him.

He and Faramir would duel and he'd kill Faramir and take his place, in disguise as his younger brother.

But no worries, Faramir would return a year later with a new wife and a band of outlaws. He'd wear an eyepatch.
