Yu-gi-oh- Gx Episode 163 (TRENDING)

I need to be cautious here because without the exact title, my information might be off. The user might need help finding the episode or a summary. Since I can't look it up, I have to rely on my existing knowledge. Also, I should mention that episode 163 is part of the World of the Memories sub-series and provide a general idea of what those episodes are like, which include flashbacks and alternate storylines.
