Suzaku Extreme lore?

[GoldStarz]

Given revelations in Shadowbringers, it's even possible that Tenzen could even have been a bearer of the same Azem soul shard that we possess, which would be further reason for Suzaku to mistake us as him. We could literally be his reincarnation.

No, Tenzen's soul is still lingering around as shown by the final quest. He's just another dude with the Echo.

Whenever a "ghost" shows up in the story, take it with a grain of salt. Ambient aetherial activity and a lot of nearby emotional instability can produce simulacrums of almost anything. Personally, I think Tenzen really was a past incarnation of WoL, and his appearance at the end of the quests was inadvertently created through the memories of WoL's own soul interacting with the power of the wards Tenzen had created.
