Oh thank god we have a spoiler thread. I need to talk with this with no limits.
I loved this show to death.
A couple of loose strands:
-Can Will now communicate with the other side like 11?
-Is 11 alive? The eggos defintely seem to point that way.
-Does Hop work for the fed now? If so, he seems to be playing them with the 11 thing. Hard to say.
-Are there more creatures in UD? There were eggs.
-Why did the monster need to come to the other side? I know he's drawn to blood, but surely he's survived in his own dimension for a while before that.
-Speaking of which, did 11's first contact alert the creature of the other dimension, allowing him to pass through?
-How did Will escape the monster for the first time? Barb woke up with the monster nearby, remember.
I have a theory that Will has latent powers which the monster was drawn to. Actually, I have a theory that the monster had been going after 11 all this time. If you look back, everyone that has been "taken" has been a kid with short hair. The adults are just killed and or eaten.
Is the monster trying to use kids for some purpose? Was it trying to get at 11 for some reason? Seems like it is attracted to blood for feeding, but it seemed to have had something more planned for Will and Barb, don't you think?
Just some thoughts.
Also, Dustin was my favorite character.
The thing that Will puked up looked just like what was in Barbara's mouth, so I'm guessing it's some kind of larva or similarly bad thing. I wonder if he's permanently "close" to the other side after being there so long or something, who knows.
I'm certain 11 is alive. Hopper seemed pretty set on getting food and putting it there, so I assume he knows she'll come for it.
I think they likely just debriefed him. I'd bet that Brenner and that scary woman were operating solo and the feds wanted to know what the fuck happened. But who knows.
When 11 first saw the creature in UD, it was messing with that yellow egg-looking thing, IIRC. I'd wager there's definitely more creatures, although maybe not the same kind of creature.
I bet it came to the other side when she tore the rift open. Maybe it never had the opportunity before that.
I doubt we'll ever know much about Will's time over there, unless it's a focus of S2.
What I really want to know (assuming S2 doesn't just totally go another direction) is what exactly Brenner was thinking with sending her to make contact after the first time she got scared. And what his intent was with UD at all. The whole "make a psychic weapon" stuff is pretty clear, but not why he was so intent on UD.
