Mike, Dustin and Lucas take Eleven back to Mike’s house and quickly realise Eleven is not a usual child, being disturbingly silent and having little concept of privacy. They can’t go to their parents because doing so would reveal they were out at night looking for Will when they were told not to so concoct a plan to have Eleven (dubbed El by Mike, seeing her tattoo) knock on the door in the morning and introduce himself to Mike’s mother and get whatever help she needed.
El remains creepily silent (Dustin and Lucas are not exactly on side with helping her) and the next morning she is adamantly against the plan, signally she doesn’t want to tell anyone as bad people are after her who will kill them all. By what we’ve seen she’s not wrong with poor Benny.
Mike skips school (understood by his very understanding mother who thinks he’s traumatised by his missing friend) to show El the wonders that this era has to offer - reclining chairs and so El can slowly become a little more talkative. We do get an insight into her terror of confined spaces with a flashback of people in an institution locking her in a small room while she screams for her father. Clearly not a happy childhood
She also sees a picture of Will and seems to recognise him. When the rest of the Geek squad return, Lucas is done with them harbouring, what he assumes, is an escaped mental patient and tries to tell a parent - only to have El hold the door closed with her telekinetic powers. This is duly impressive to the three kids who love all things magical and super-powered. They’re totally on side with helping her hide out now. They also thinks she knows where Will is - and she reveals via DnD models because communcation is somewhat difficult for her. Will is hiding from a monster
Jonathan and Joyce are dealing with missing Will… badly. Joyce is imploding messily and emotionally and it’s painful to watch. She’s making flying, melting down all over chief Hooper and convinced that the weird phone call she received was from Will, though it did fry her phone making her go to her place of work, get an advance because she spent all her money on missing papers, to buy a new phone. It’s really excellent acting because it is terrible to watch her completely implode
Jonathan is trying to hold it together and support his mother which is- he goes to see his dad Lonnie to see if Will ran away him. Clearly not - though we do get a suggestion from Lonnie that Joyce is partially to blame for their break up. I’m not entirely convinced as he’s pretty much the worst from what I can see.
We do get a flashback into just how much Jonathan supported his little brother in the face of their parents’ arguing and how Lonnie was trying to force Will into having hobbies he wasn’t interested in but Lonnie considered better or more appropriate (sports vs computer games it seems). It seems Jonathan has been a rock for this family for some time.
