32 Very Important Details We Noticed in the Totally Insane Stranger Things Season 3 Trailer

The trailer begins with the gang using Eleven's powers to help surprise Dustin, who has apparently been away for long enough that they'd go out of their way to make a "Welcome Home" banner. We assumed the season was starting at the very beginning of Summer, meaning school had only just let out, but that's clearly not the case.

Dustin is wearing a shirt and hat that say "Camp Know Where," which has a logo covered in telescopes and computers. Apparently, he's returning home from science camp, which must mean the season is picking up halfway through what looks like a fairly normal Summer.
