What Happens To Will In The Upside Down And How Does He Escape?

While whetherEleven created the Upside Downis a big question, there are a few other questions relating to this memorable setting: what happens to Will there?

When Will rides his bike home one night, a Demogorgon, one of themost terrifyingStranger Thingscreatures, takes him and forces him into the Upside Down. It seems that he spends a week here, trying desperately to survive and to figure out where he is and what’s going on.

In season 1, episode 8 called “The Upside Down,” Joyce Byers (Winona Ryder) and Jim Hopper (David Harbour) go into the Upside Down and see Will in the library. When he gets back home, a doctor checks him out, and everyone is happy and relieved that he seems to be fine.Stranger Thingsis always full of twists and turns, however, and Will goes to the bathroom and throws up a slug and sees the Upside Down again. This suggests that the evil is far from over and he is still being affected.

This is one of the most compelling scenes from all of season 1. Will looks genuinely afraid and emotional, and it’s clear that he feels guilty over potentially worrying his friends and family. He doesn’t want them to know the truth, but asfans know, there are manyscary scenes inStranger Thingsand the show only gets more interesting and intense.
