Will we get this parallel this season?
Looks like Will might be exhausted using his powers (maybe he was spying on Vecna? And maybe it led to that last clip in the teaser?):
So it looks like Mike might be tortured, too, seeing someone he loves suffer. We've seen how he's dealt with it before.
Maybe we'll get a callback to this:
I don't think he would BLURT it out though. He would just be... super-protective of Will and his own frantic Mike way lol. A perceptive character (Joyce? Robin? Murray?) might figure it out!
But I think it'll be Jonathan or Nancy, because they were there when it first happened. I think Jonathan is more likely. I'd be happy if Nancy knows, as she could talk to Mike about it. I want to see more of the Wheeler siblings being close! Mike is fearful of losing El, Holly, AND Will and needs his big sister to help him through this!
