A frantic, half-audible call from Lucas reaches Mike's basement: the lab knows about Eleven and is on its way.

Mike interrupts Karen's phone call to ask about repairs, realises the van outside is the lab, and leaves with a one-line exit.

The boys race through Hawkins on bikes with lab vans closing in, until Eleven sends one flying overhead.

After the chase, Lucas takes back calling Mike a traitor and the party's rule gets said out loud.

Shown a photo of a girl with a shaved head, Karen and Ted deny everything until Brenner tells them Mike is in danger.

At the station Joyce lays into Jonathan for hunting the monster himself and reminds him he has a family.

Troy's mother storms the station demanding an apology, and Hopper learns a shaved-headed girl who hangs with the losers broke his arm.

Steve refuses to laugh at jokes about Nancy and Jonathan, calls his friends what they are, and walks out of the pharmacy.

Nancy uses the AV room ham radio to reach her brother; the boys debate a Lando Calrissian trap until Mike finally answers.

Dustin paces and panics that the chief set them up, Lucas has had enough of Lando, then headlights appear.

Nancy hugs Mike and notices her dress; the boys explain the Upside Down with a flea and a tightrope; Eleven reaches and comes up empty.

At ten on a Saturday Dustin phones his science teacher for sensory deprivation tank plans, and learns they need 1,500 pounds of salt.

Setting up the pool, the Wheeler siblings swap confessions, Mike reveals what Eleven eats, and both deny any crushes.

Fitting the goggles, Joyce tells Eleven she is brave, thanks her for Will, and promises to stay with her the whole time.

In the void Eleven calls Barb's name and finds her; she surfaces screaming one word while Joyce holds her, then names Castle Byers.

Eleven finds Will in his fort and relays Joyce's message to hold on; she comes out of the water shaking and is told she did good.

Hopper wants Joyce to stay back; she refuses outright and tells Jonathan to watch the kids before they head for the lab.

Hopper's plan is to let himself get caught; guards swarm them at the gate as The Clash plays out the episode.
