I had an interesting idea. Iran we know that Yugi and Yami were linked because of sharing a body so? What if because since their bond was so strong that traces of their bond or link was still there that Yami and Yugi could tell when one was in danger or notice something wrong. Maybe even somehow speak to one another faintly and at a distance. Though the sensing ones danger almost limitless no matter where they are. Well as long as they are in the same city or something like that The more away they are the fainter it gets i guess. Pretty much showing that the Yami is beasically his other half that if he passed instead of being locked away, Yugi is almost like his reincarnated self. Atleast thats how i thought about. And i know im going deep into it. Its yugioh. rewatching Yugioh and the thought occurred.
