15Is Matthew Modine's Dr. Brenner really alive?
In season one we last saw Dr. Martin Brenner, the unscrupulous senior research scientist and director of Hawkins National Laboratory, being attacked by the Demogorgon. While his death wasn’t confirmed, it certainly appeared he was another victim of his own crimes, because didn’t seem possible he could have survived.
when Eleven and Eight went to kill one of the men who worked for Brenner, he begged them to spare his life. That included offering to help the two of them locate Brenner, who he said was still alive.
Was this just the desperate pleadings of a man who was doing anything he could to save himself? Did he honestly--but mistakenly--think Brenner is still alive? Or was he telling the truth, and Brenner is still out there somewhere? If so, could he still be working for the government? Does he still pose a risk to Eleven and everyone else in Hawkins?
If Brenner survived his attack, does he want revenge? Could he open up the portal to the Upside Down again? Will season one’s main human villain be season three’s as well?
