[Arwen Imladris]

Ahh! Another What if topic! Oh well. Everything would have been different. I suspect that they would have gone to Lothlorien and then travelled down the Anduin on boats. He would have simply told Boromir to either go home or go the rest of the way with the fellowship. When the orcs attacked, Gandalf would have been able to save them, even if it ment hidding in trees again. From there, they would have, um, called the egals to drop them off inside mordor and then proceeded to mount doom.
