Yami Yugi (Atem) Character Impression

Due to the Yu-Gi-Oh! Out of Context series presenting panels out of chronological order and lacking crucial information characters often do not appear in the same light as they do in the source material.

Chapter One: Don't Worry I Can Fly a Helicopter
In the first chapter the Pharaoh appears in six panels as well as the Chapter Banner Art. He is seen to be: confused; telling people off for aiming yo-yos at people; casually stating he does not know who he is; calling out Grandpa whilst dressed in Ancient Egyptian attire; squirming in disgust and groggily claiming to be alright.

Based on these random panels we are given the impression that Atem is suffering from severe memory loss (which is canonically accurate).
