Stranger Things Season 2: 13 Big Questions We Need Answering

2. Can She Return?

It's been confirmed that the majority of the cast will be returning, meaning we can look forward to spending more time with the likes of Joyce, Mike, Lucas, and Dustin. Mostly Dustin, because who doesn't love that kid? Maybe he'll get his teeth in Season 2? Anyway...

The one they're keeping quiet about is Millie Bobby Brown, who plays Eleven, with no word yet on whether or not she'll be back. It's difficult to imagine the series going ahead without its best character and breakout star, so we'll take it as a given Brown will return, but just how can Eleven come back?

Are El's scenes going to take place in the Upside Down, or wherever else she is trapped? It'd be a shame not to see more of her alongside the rest of the kids, so is there a way of getting her back to Earth for a reunion? And just what is going on with her and Hopper - is that a relationship to be explored more in Season 2?
