That description sounds like a description of both Arwen and Eowyn. And since there is no mention of an actress playing Eowyn in the press release, it sounds like they may be combining those characters into one. I certainly hope we don't see Arwen coming on the journey with the travelers, that would be incredibly stupid.

I understand the need to over-emphasize the love of Arwen and Aragorn, but I think that could be effectively done with flash backs to their first meeting and their engagement on Cerin Amroth.
