Finally, after waiting a year and some change, Stranger Things is back. We know you’ve canceled all your Halloween weekend plans and cleared your schedule to binge the second season tomorrow, but before it hits Netflix, there’s some lingering questions we need to revisit.

The first season of the Duffer brothers’ coming-of-age horror series left its mysterious sci-fi world suspended in plenty of mystery. For one, everyone’s favorite Eggo-loving kid with superpowers (Millie Bobby Brown) vanished into the ether, leaving us anxious to find out what she’s been up to since. And the final scene of Will (Noah Schnapp) puking up a slimy slug was alarming, to say the least. What’s going to happen to him? Before we dive in to our Stranger Things 2 binge tomorrow, ScreenCrush’s Kevin Fitzpatrick and Oliver Whitney rounded up 11 (get it?) of the biggest unanswered questions, and some ideas for how Season 2 might try to address them.

Stranger Things 2 hits Netflix on Friday October 27 at 12:01 am PT, 3:01 am ET.
