Yeah sorry, in terms of main characters I somewhat agree with @blueturtle that we don’t spend ages on rumination, but also I think you have to consider no one wants to bring it up?
Mike is still obsessed with Eleven but she is presumed dead and he’s traumatised. We can assume the period where
Dustin and Lucas thought he should be talking about her is gone now so it’s internalised.
Will knows it’s not over and has done since he spewed up that bug last Thanksgiving or whatever, AND he’s being chaperoned by his mum so he isn’t really wanting to talk about it due to trauma.
I mean the four of them are trying to move on with their lives. The older kids clearly don’t want to necessarily talk about it because there’s a whole love triangle there for Nancy and she does in fact make it clear to Steve that they SHOULD be talking about stuff (maybe that’s more like episode 4 or 5 though). <-- for eps 4,5,6 maybe?
Hopper’s trying to keep a lid on Eleven.
So what I’m saying is they all have their personal reasons for not even talking about it with each other. We know that if people overheard it might mean jail for any of them. They can’t freely talk and frankly in many ways they don’t WANT to talk about it.
(Joyce is definitely still talking about it with My Two Dads / Carter Burke and Hopper so in that sense it’s alive?)
