In LOC, Semirage wondered about the bond between the Warder and Aes Sedai during the torture. I don't believe that Alanna is a Darkfriend. First, see seems almost caring at the end of LOC when she asks Rand how he can bear the pain from the wound in his side. Why would a Darkfriend bond the Dragon Reborn anyway, to give him even MORE strength? It doesn't make sense from a Darkfriend's point of view. I agree with the thought that it was because Rand is a Tavereen.
