By Friday, Nov. 11, those in the know are starting to form alliances. Joyce and Hopper team up and pay a visit to Terry, learning about her daughter for the first time. Eleven is terrified of what she's seen and heard during her time as a test subject, so she interferes with the boys' search for Will, resulting in a temporary split. Jonathan and Nancy team up to track the monster that killed Barb, and Nancy gets sucked into the Upside Down, only escaping with Jonathan's help.
Agents pursue Mike, Dustin, and a recently returned Eleven, and all of the heroes finally team up. Eleven is able to see Will — and Barb's body — in the Upside Down. Even Steve joins in the fight, teaming up with Jonathan and Nancy to lure and attack the monster, but it disappears, wounded. El is able to escape agents sent to capture her and defeat the monster but disappears in the process, and Joyce and Hopper rescue Will from the Upside Down.
