Episode 9: "The Lost Brother"
This is the most evocative title in the whole batch. It seems unlikely that the Duffer brothers will once again put us through another season of the boys searching for their friend Will, so who will be the new "lost" brother this season? There's the possibility that "lost" could mean missing, or it could mean -- brace yourself, Barb fans -- dead. What if the finale of Season 2 delivers a big character death?
While Mike, precocious brother to Nancy Wheeler, is of course a possibility, I think the smart money has to be on Jonathan Byers, the misfit brother to Will and Nancy's other romantic suitor. I don't think the Duffer brothers will kill off one of the younger characters on the show -- the series will want to keep its Amblin-like tone of innocence -- but I think some of the older characters could be on the chopping block for Season 2, and Jonathan seems the most likely to sacrifice himself to either save Nancy, his brother, or even Eleven, if she ever returns from her Eggo-filled sabbatical in the Upside Down.
