Hawkins Lab Superior Chalmers: Good lord what is happening in there?

He gestures toward the large gaping Upside Down gate in the lab basement.

Brenner looks at the gate hole and back at the superior.

Brenner: Aurora Borealis?

This thing keeps following me around bargain bins at the stores I go to.

Jagged Edge (1985)

I think in the book Suspicious Minds we’re going to find out that Dr. Brenner has pyrokinesis and/or that he has a time based or location based leaping ability, which is how he avoided being attacked by the demogorgon. 

I also think that Dr. Brenner’s connection to the Soviets is that he is selling information in return for the experimental drug that he’s using in the MKUltra project trials, sort of like Doc Brown making exchanges with the Libyans for plutonium.
