Might belong more on the discussion thread, however it appears there may be a typo near the beginning of the ‘Flesh From Bone’ Quest. Upon approaching the entrance to the church/building where Lorath and Taissa are waiting, Meshif says “Ah, you’re here! Deckard is inside with your friend.”
I paused when the line was delivered, confused as to who he could possibly be referring to as I was unaware of a character with the name Deckard, and a small part of me wished that I had missed some previous lore that brought a part of the Cain bloodline into Diablo 4. However, inside the building are just boring old Lorath and Taissa 
.
Hidden easter-egg-homage to our once beloved Deckard Cain? Perhaps
