Btw, what if Pharaoh Atem/Yami Yugi met Divine Djinn when he was a child? 

Since he was born in 3000 B.C., and that Shadow Djinn was born in 3003 B.C., Divine would be the only one who Atem knew in his past. Shadow Djinn would remind him of her, since she is technically a physical shadow manifestation of her. 

We would have to remember that Divine Djinn is dead, and only Shadow Djinn roams around as a spirit.
