In another room, Hopper is being interrogated and reveals everything he knows about Eleven and the Laboratory's experiments. However, Brenner's men want to inject him with drugs so it looks like Hopper is a junkie who lost his mind and doesn't know what he's talking about.

Meanwhile, Joyce and Hopper set off to find Will inside of the Upside-Down, and they put on special suits to protect their bodies from the toxic atmosphere.

Mike is talking with Eleven at the school where they are hiding out. Mike tells El that everything will be okay, that his parents will take her in and she'll be like family.
