Gearing Up For Stranger Things Season 2? Don't Forget How Season 1 Ends

Dr. Brenner (Matthew Modine) is the director of the Hawkins National Laboratory. He had taken a young Eleven away from her mother and performed numerous experiments on her over the years, manipulating her by acting as a father figure and constantly pushing her boundaries to dangerous limits. When Eleven escapes the lab, Brenner spends the duration of the season looking for her and trying to keep the operation under wraps. He finally finds her during the season finale — also coming face-to-face with the Demogorgon. The monster attacks him, but we don't know for sure if Dr. Brenner is really dead.
