Will made his real presence known by communicating with Joyce through the electricity in their family home -- first over the telephone, and later via Christmas lights. After travailing to the Upside Down, both Joyce and Hopper found Will and brought him home. The season ends at Christmas, with Joyce, Jonathan, and Will all enjoying the holiday together -- until Will escapes to the bathroom and throws up what looks like some sort of slug creature that resembles something from the Upside Down. The episode ends on a cliffhanger, leaving us to wonder what's really happening with Will.
What's next? Will is arguably the biggest question mark for Season 2. Is actor Noah Schnapp -- who barely appeared in Season 1 -- up to the challenge of portraying the youngest Byers kid? And how well will he mesh with the boys who play his best friends? The trailers for Season 2 tease Schnapp's heavy involvement -- he appears to be having fully formed visions of the Upside Down, including what looks like a new, Lovecraftian tentacle monster. Is this an evolution of the Demogorgon, or something entirely new? And are these merely visions, or is Will physically transporting back to the dimension that previously imprisoned him? According to trailer and other behind-the-scenes information, it looks like he's in for a heavy round of probing.
