10 Unanswered Questions From Resident Evil 7
3. How Could Ethan Talk To Jack & Zoe?
Near the end of the game, Mia finds Ethan encased in the mold, which triggers a surreal sequence from Ethan's perspective where Jack, now a regular man free from the mold's influence, begs Ethan to set his family free from the infection.
It's a pivotal scene that flips much of what we knew on its head, but how, exactly, are we watching it? Is it a dream? A vision? Or what?
The Likely Answer: It seems probable that while Ethan was within the mold, he connected to a psychic hive mind of sorts, allowing him to interact with other people affected by it, in this case Jack and Zoe.
Jack's dead at this point but his consciousness appears to have been retained in some form by the mold, allowing him to reach out to Ethan...or something?
As for why Marguerite's nowhere to be seen, that's a whole other can of worms.
