‘Stranger Things’ Season 2 Update: Sequel Focuses On Secrets Of The Upside Down, Millie Bobby Brown MIA In Collective Con

"Stranger Things" Season 2 is set to return this year and fans may be delighted to know that the Upside Down will get more highlights. There's a lot to explore in this hidden parallel world and hopefully, all questions will find answers this coming season. Meanwhile, actress Millie Bobby Brown went missing in action during the Collective Con held in Jacksonville, Florida but she has a fair reason why.

"Strangers Things" Season 2 will see more scenes in the Upside Down according to series music composers Kyle Dixon and Michael Stein. Dixon and Stein spoke during recent South By Southwest Festival in America where they revealed that fans will see the Upside Down as a place, Express reported. That said, fans should get ready for more weird soundtrack too!

It remains to be seen if any of the "Stranger Things" Season 2 will be trapped in the Upside Down again or will revisit the dangerous place. But what's known is that Will Byers who has spent all his time on season 1 in the dark world is now suffering from what seems to be a post-traumatic stress disorder. Additionally, he might be involved in another trouble related to Demogorgon spawns living inside his body.

This is evidenced in the season 1 finale where Will coughed up some strange mucous that's totally not normal. Apart from this incident, "Stranger Things" Season 2 co-creator Matt Duffer also said that Will is going to see some Upside Down images but he needs to figure out if those are real or not. So, fans should wait how this part of the story will progress come Season 2 of the hit Netflix series.

Meanwhile, Brown who plays as Eleven missed to attend the recent Collective Con because she had to take a much-needed rest after working long hours for "Stranger Things" Season 2, Comicbook reported. The actress took to her official Instagram to apologize to fans for not being able to make it to the conference. She made it clear that this is not something she usually does and she doesn't plan to do it again in the future.
