Moments of pure relaxation had escaped Khan's life for many years. The Slums couldn't provide them, Ylaco's training camp didn't either, and everything past that had been a complete mess which had left him in a constant tense state.
Liiza had been the only true exception but experiencing that happiness had ended up cursing Khan. Reebfell should have given him peace, but he had never fully accepted it since he had always known that his departure was set in stone.
Jenna could come close to Liiza, but her relationship with Khan was complicated. He could completely relax with her, but he also had to put clear limits on his behavior. They both had.
However, when everything went away and the countless problems of the universe stopped shouting, Khan could see himself as an ordinary man. A man who happened to like a woman.
