After Henry finally realised his memory had a serious problem, all he felt was curious.
He was curious about Richard's sister who was betrayed by him.
He was curious about what their relationship was back then.
How did he betray her?
He confirmed those nightmares might not be just nightmares, but also reality. They must be his forgotten memories about her. But none of them were pleasant. That's what made him worry. As Richard said, was he really a bad person?
On that same day, Henry lay on his bed thinking many things but was actually having nothing special in his mind. He looked out of the window and the bright moon showed up from the window. The moon was bright. It was beautiful. He kept looking at the moon until his eyes started to hurt. He wiped his eyes, walked to the window and closed it, thinking he should go to sleep.
