Summary: Elrond's feelings at Arwen's wedding.
Elrond smiled at seeing Arwen and Aragorn so happy. Any doubts he ever had at their union were dispelled upon seeing how much joy it brought to them both. That Middle-earth was now a safer place than it ever been during Aragorn's life only added to their happiness.
Elrond was also terribly upset that day. Arwen had been torn away from him and when he went to the West he would never see her again. He would not be there to see how she prospered, nor to greet his grandchildren.
But today he could be happy, tomorrow he would grieve.
