I must get Sauron's PR person

[the phantom]

but Frodo said something about "Only Elves can escape now, if the Sea is wide enough to protect them."

I remember reading that quote not too long ago but I never got around to thinking about it very much.

I can't remember, when does Frodo say that? Is it after he crosses into Mordor? If so, then it's possible that his thoughts are so clouded with the darkness of the ring that he can't see any hope for anyone escaping the shadow. That could explain his comment.
