After Steve gets sucked into the Upside Down, Nancy, Robin, and Eddie follow him into the watergate and help him fight against a swarm of Demo Bats, which are small creatures that resemble the Demogorgon that can fly. However, when even more Demo Bats rush toward them and begin guarding the gate, the group is forced to find another way out of the Upside Down. Luckily, they find another gate in Eddie's trailer. Robin and Eddie make it to the other side, but just as Nancy and Steve are about to join them, Nancy gets put into a trance by Vecna, who shows her visions of Barb's death and his own past. This leads us to think Vecna could be out to get Nancy next.
