'Stranger Things' season 3 post-credits may have teased the return of the evil Dr. Brenner and a cooperative Demogorgon

While a majority of fans are hoping that Hopper is the 'American' mentioned in the post-credits scene, they aren't ruling out the possibility of Dr. Brenner still being alive and kicking

This article contains spoilers for 'Stranger Things' Season 3

The post-credits scene for 'Stranger Things' season 3 ensured that two things will be part of a potential season 4- The possible return of David Harbour's Jim Hopper and that there was a Demogorgon that the Russians had managed to capture and keep well fed. 

The return of the Demogorgon raises some tantalizing questions. How did the Russians manage to get their hands on one of the creatures while still trying to figure out a way to open the portal? Were they in Hawkins all the time while these occurrences happened? Was Dr. Brenner (Matthew Modine) still alive assisting the Russians. Last we saw, he seemed to have met his fate at the hands of the Demogorgon.  Except, that his death was never really confirmed onscreen. 

Leaving us to speculate:

What if the Russians managed to put a spy in Hawkins and he/she managed to get hold of the Demogorgon?

Possibly. We saw that Russia had some secret service muscle doing their dirty work while they were trying to perfect the cannon that would open the portal to the Upside Down. By the end of season 2, this spy may have managed to get his hands on one of the hurt Demogorgons and would have fed it well enough to nurse it back to its full strength so as to use its help to open the portal.

Demogorgons are...kinda like pets (Outlandish, but we have proof)

Remember Dart, the demodog? Dustin's (Gaten Matarazzo) pet in season 2. The boy did take care of it when it was a mini-version. In the final battle, Dart hesitates to attack Dustin and Co. when they are trapped in the Hawkins lab. What if the Russian scientists did the same? Technically, they aren't cold-hearted like the military chaps they are surrounded by.

Genetically mutated

Remember the green goo that Steve (Joe Keery) and the team managed to get their hands on? That gunk also powered the cannon and was instrumental in cracking open a bit of the portal. For all we know, they would have tried experimenting on one of the Demogorgons. It did look awfully human by the way. 

With Eleven's powers gone (not for long, we hope), Hopper presumed dead and the Russians still active, our heroes have their hands full. How will they manage to put down the Demogorgon, the Russian militia, and a possibly alive Dr. Brenner at once? We don't know, but we can't wait to find out.

'Stranger Things' season 3 is available for streaming on Netflix.
