Given that the Duffers are hoping for 4-5 seasons of Stranger Things before calling it quits on Netflix, they have to bring Brenner back at some point, right?
None of the footage so far has pointed to a return from Dr. Brenner, but we can always speculate.
There’s really only one character that we know won’t be back among the living in Hawkins at this point, and Brenner didn’t come to nearly as definitive an end as poor Barb.
The Duffer brothers already admitted that some fan theories are correct, so it’s entirely possible that some of us will figure out what’s next for Brenner before the show even tells us.
