First Time Watcher: Is David Harbour An Idiot?

I’m only like five episodes in, and I know, long overdue… I’m loving the show so far but I just watched as Harbour discovered the fake corpse and am wondering why he didn’t immediately inform his team? Like why does he not at least tell Will’s mom? He just goes barging in to Hawkins Lab, and the whole time, I just knew he’d be caught, because how the hell was he going to get out of there anyways? He was either landing in the upside down or in chains, no doubt.

And then, I can forgive all that because he doesn’t know who to trust or whatever, but if I found myself in front of that weird creepy portal thingy the last thing I’d do would be to go up to it and touch it, like what the hell?

Also here’s my theories so far, please no spoilers:

Harbour’s daughter, Sarah, is Eleven? Eh? Probably a red herring tbh but I’ll be damned if that little girl (Sarah) is not in any way relevant to the story.

Steve is gonna slowly but surely become a far more likeable character

Will is gonna be saved by the end of the season

Barb is gonna be dead by the end of the season

Will’s brother is gonna somehow be involved in saving Will

Will’s birth father is gonna come around and agree that some funky stuff is going on

Idk what else but I am loving the show.
