In the eight-episode first season of Stranger Things, Netflix's 1980s sci-fi/horror/nostalgia mixtape, a faceless monster terrorizes a suburban Indiana neighborhood, shady government suits conduct paranormal experiments, and four kids make a mysterious friend who can do powerful things with her mind. The binge-worthy, reference-heavy show, from Wayward Pines writers Matt and Ross Duffer, connects many of the dots in satisfying ways, but some things remain maddeningly unclear.
In honor of the Spielbergian series' breakout character Eleven, here are a bunch of questions we absolutely need answered when Stranger Things returns for Season 2.
1. Who is Eleven's biological father?
The show heavily implies that Eleven is a child born to a woman named Terry Ives, who underwent the last gasps of the super-secret MKUltra program. But who's her daddy? Matthew Modine's Dr. Brenner makes Eleven call him "Papa." Is it possible that he was sleeping with his MKUltra subjects and is the (horrible) biological father as well as a surrogate one?
