What's going to happen to Eleven?

The "Stranger Things" Season 2 trailer confirms that Millie Bobbie Brown will be back as Eleven. In the trailer, there's a close up shot of Eleven with her nose bleeding, which indicates that she recently used her telekinetic abilities.

The last time viewers saw Eleven, she gathered up all of her powers to defeat the Demogorgon. She vanished into thin air, but a one-month time jump showed Chief Hopper placing some Eggos in crate in the middle of the woods.

It's possible that Chief Hopper will be the one to discover Eleven's whereabouts in Season 2. "He (Hopper) may understand that Eleven exists in some form. And so he's got this box out in the woods where he gives her food," actor David Harbour told Mirror.

There is also another scene of Eleven in the human world, and sporting a full set of hair. It's uncertain where the scene takes place, but it is presumed that it's in Joyce Byer's house. After all, given their brief mother-daughter bond in the first season, it is likely Joyce welcomed Eleven into her home.

What's that monster?

There's a new monster and it's bigger than the Demogorgon in Season 1. It's a big creature with multiple limbs that appear in town on a stormy night. The monster is seen first-hand by Will Byers.

Is Will the subject of a new experiment?

In one scene, Will appears to be wearing a hospital gown with sensors attached to his head. There's a doctor examining him, while Joyce sits beside his son. This scene is being monitored through a security camera, and it is presumed that the government is once again observing the strange activities in the town.

According to Comicbook, it's either Will is getting treatment at a mental institution or getting evaluated and tested by scientists at the Hawkins Laboratory.
