"Spock..." Uhura voice was a little hurt. It was so obvious that the fact that his home world was destroyed in these dreams got to him. Even if it weren't for the look on his face as he looked past her, she would have assumed it because of the way he took such an intense interest in the dreams and spoke of running away into space with Kirk.
Uhura reached out to touch Spock's face and ran her thumb down his cheek. She wasn't really sure what there was to say, but she wanted him to know that she was there for him.
