Nunnally;
"...A Knight of the Round?"
Indeed had you not expected me to return with such rank, and to top that off, I was a Count of Britannia. I was indeed impressed with what I had achieved, and so was Milly. I had knelt down on one knee, taking your small hand in my own as I smiled toward you, even though you wouldn't see it. I had made a promise, and I had kept it, I just wanted you to believe that. I was so happy when I saw you smile. I hadn't expected it since I worked for your father, the same man that had banished both you and Lelouch, after the death of your mother. He'd even pronounced that you and Lelouch were both dead, I knew you wouldn't forgive him.
The time I spent at the school, I rarely left your side when you were out in the school grounds, most of the other students would stop and talk amongst themselves when they saw you talking with a Knight of the Round. It was definitely a shock, but you always laughed gently at their oblivious state to what you really were, a princess.
"Nana... I have to leave."
I remembered how your gentle mask was spoiled by a look of shock and a delicate frown; it instantly punched me in the heart as you asked why. You had even set up a special dinner for yourself, Lelouch, Suzaku and Milly and I. Just to see us all happy for once, since the tension had grown. You weren't the only one that was shocked; Milly had desperately tried to tell me not to go to battle. I couldn't abandon my duty. I had come all the way to Area 11 to fight, not to visit. You knew that, and Milly knew that, but you didn't want to accept it. You had already lost Shirley, and Euphiemia, I doubted you were not even sure how to deal with Suzaku or I dying on the battle field, nor would Milly know how to handle it.
"I promise I'll come back."
"Cross your heart..."
I had crossed my heart, and shook your hand. You had nodded, a smile forcing its way across your face, through I could still feel the tension. My attention was then lost to you as I looked across at Milly. She was holding back tears as I knew she longed to reach out and never let me go, I felt the same way. She had called off her engagement, just to move on with her life, she didn't care for nobility any longer, her pain and suffering of losing her friends in this war had blocked her heart off for what she had once longed for. I had embraced her tightly before leaving alongside Suzaku, our backs turned to you and Milly as you waved goodbye. It was a last goodbye, and we had turned our backs.
