He stayed on Earth to help with the Vulcan relocation and complete a census of survivors. He also spent time with his younger self counseling, as well as observing, the younger man. He saw the looks and touches between his younger version and Uhura. He knew what they meant. He remembered them well. He remembered the thrill of the first blush of love and remembered the feel of Uhura's body against his. He envied them in the discovery of that love. He hoped he would be around to see them fulfill what he knew was to come and acknowledge it.
