Last guess for the night:
Mithalwen, as the first person to have a Barrow-Downs dream analyzed by our own Dr. Elempi Dream (as far as I can tell). The dream was werewolf related, and not posted on Wilwa's dream thread, but instead on the "Your LOTR Dream" thread by laziieye.
And I'll need some rest before puzzling over this one anymore.
EDIT: My mistake. That would be
Cailin, not Mithalwen, whose dream was analyzed. Mith made a werewolf related comment that was incorporated into the post...
Good night.
