I don't own LotR
Hundreds of spectators crowded the walls. They had heard the horn and went running, the guards all alert and ready. When one cried that he saw the Steward's son and his wife riding back to the city, everyone wondered what had happened. But as the group drew closer, people gasped equally in terror. The black arrow was easily seen.
The people were silent as the shocked couple rode up the streets to the Houses of Healing. Women cried at the sight, and children gasped. Some recognized the occurrence and immediately hung their black flags: an heir had died.
Once inside the Houses of Healing, Wyniel collapsed onto the floor, still protecting her child from the fall. She wouldn't let him go, but didn't need to. The nurses could tell that he was dead and there would be no remedy. Wyniel herself, however, was bleeding from the chest and needed attention. The would was shallow, but deep enough to infect. After a long time, Boromir was able to take Ecthelion into his own arms, and Wyniel was cleaned and stitched, the entire time staring at her lost child.
