It was the halfling Meriadoc who finally told Eowyn how Boromir had fallen. She had not seen him since before his departure for Imladris, little suspecting that he would never come to her again.
It was for Boromir's sake that she took Meriadoc into battle with her - both to allow the halfling the same chance at valour she herself desired… and to keep close one her lover had cared for.
She suspects that she was able to love Aragorn and Faramir only because she previously loved the one's close companion, the other's brother. For love him truly she did, and mourn him she always will. She loves Faramir no less, of course, but not in the same way.
She is happy. But she will never forget the ones she has lost. Not as long as she lives.
