Well. She didn't fly into a rage and kill them all, which is good, and her examination should conclude that their side of this war is justified, which is good, and she can get the other host here safely without sending the boats back, which is very good. But it doesn't seem like there's a way to get the boats back to Alqualondë without her going to Alqualondë and hearing a story that will then probably make her fly into a rage and kill them, which is bad. Perhaps they can win the war here first.
She is actually not the principal complication here. The principal complication is that Father, while he'd been dissuaded from talking with a Power from a different world who'd just calmly stopped them from doing this, would probably not stay dissuaded, and that having the cousins on the other side of the continent seems like an unstable compromise, and that he's not sure if she can hear him while he's trying to stabilize all of that.
The Fëanorian tightrope, Findekáno used to call it. It was a wider tightrope before you denounced my father and named yours the King, Maitimo wants to say, but that can wait.
