At the moment, it remains unclear as to whether or not Jim Hopper (David Harbour) will return following his possible demise in the season three finale.

However, it seems like a certainty that Dr Brenner (Matthew Modine) will be making a comeback, leading some fans to believe that Eleven and Hopper will be reunited.

How? Well, one Reddit user believes that Eleven will seek vengeance against Brenner for experimenting on her in the first season. And, when she finds him, she will learn that Branner hasn’t just survived their last encounter – he’s thriving, based in Kamchatka, and working with the same Russians we saw at the end of season three.

You know, the Russians who were feeding prisoners – albeit “not the American” – to a captive Demogorgon? Those Russians.

You can see where this is going. Our Redditor believes that Elle will seek to bring Brenner to a very grisly end – but not before she learns that his mysterious “American” captive is someone she knows very well. Someone like…

Yeah, Hopper. Go figure.
