Arwen at Pelennor Fields?

[The Saucepan Man]

Hmm ... I'm not sure that Arwen's expanded role was just to stop Liv Tyler sitting around twiddling her thumbs while being paid loadsa dosh.<P>It seems to me to be fairly likely from what I have read on this and other sites that Arwen will turn up at the beginning of the next film with Aragorn's banner and Anduril re-forged (Aragorn does not already have it). It also seems fairly certain that Halbarad and co are out.<P>That being the case, it's unlikely that Arwen will just head off back to Rivendell having given Aragorn his bits and pieces. I suspect that she will accompany him on the Paths of the Dead (if she is there, why would she not go with him) and that she will be there at Pelennor Fields.
