[the mortal elf]

I'm convinced that she went to Lothlorien, mainly because of four bits of information.<P>1. I think it was Manwe Sulimo who said that there were pictures of Galadriel brushing Arwen's hair.<P>2. The extended edition scenes where she's going to take Narsil.<P>3. Elrond's and Arwen's expressions when she leaves. She looks determined and fixed on her course. She doesn't look like she's about to break down in tears because she's leaving the love of her life behind. Elrond looks like his heart is about to break. He would be a bit happier if he knew that his one and only daughter were going to the Havens and then to Valinor, where she'd be safe.<P>4. Haldir. At Helm's Deep, he says, "I bring word from Elrond of Rivendell...." Since he was from Lothlorien, it would be highly unlikely for him to know what Elrond wanted unless Arwen told him or got the information to him.
