Question: After Frodo has been stabbed by the Morgul blade and Arwen is taking him to Rivendell, right after she uses the river to sweep the Ringwraiths away, Frodo makes a wheezing noise and begins to look radically worse. Why does Arwen get off the horse, lay him down on the bank, and cry? Why doesn't she just speed off to her father who can cure Frodo? Why the delay?
Chosen answer: If she had started riding off w/ him, he could've died on the way there. Instead she stopped and got off the horse and prayed to the Gods to "give him the grace you have given me." Basically to save his life was what she was asking for.
