The pic says it all, "Dustin!"
This episode should have been titled, "poor choices"
Eleven is proving how "not stupid" she is by breaking every single "don't be stupid" rule.
Dustin is breaking his own "don't be stupid" rules by harboring a visitor from the upside down who was a stowaway aboard the SS Will Byers...
Mike is mean to Max for literally no reason, Steve gets jealous of Jonathon and Nancy... again. Get this, because Jonathon drove her home... because Steve asked him to? What the heck Steve? how does that even make sense? Jonathan and Nancy (mostly Nancy) is still sick of the BS and devises a plan when she spots who may or not be the spiritual essence of future Eddie Munson listing to Metal on a walkman...
Joyce does some terrifying coloring and eats bologna and I'm not sure which is more frightening to me personally but she figures things out too late because Bob has given Will the worst good advice ever and he gets the old "John Locke" treatment from this show's smoke monster :)
