the character of Peter Quint

So when Dani arrives at the manor we hear these descriptions of him from the others as this cad and a thief, but then we find out that he wasn't actually a bad guy at all - just severely damaged and in a difficult situation.

I still don't fully understand though what we are supposed to make of his character. For instance, that scene with the jealous rage - what was that? We see in the morning after Becca gets out of bed that he was actually trying to be controlling, definitely not taking her refusal to get back in bed lightly, and I specifically rewatched the scene with the batter tasting in the kitchen - the first time I watched the ep I missed how he was just glaring.

Then he comes back a few days later acting like a different person, and when called out on his behavior, he actually says "I don't know who that was" - so does that mean he was possessed when it happened?? I mean, if he really was this possessive, controlling type, I wish the show did more to establish a pattern of such behavior - one isolated occurrence, especially in that friggin' spooky house, is not enough.

Then already after we learn that he is dead there is a flashback to the scene of his night with Becca, and we see him crying... So I thought in that moment that he exists outside of time (kinda like Hannah does) and is crying because he already knows what will happen. Or did I interpret that wrong? (well, "interpretation" may be too big a word, it was really just a momentary thought) Was he not crying when it actually happened the first time, but only when he revisited the memory, so it wasn't the "real" him in bed? Kind of like what Flora does in her memories with her mother where she repeats she should be "littler"?

So then it appears that their entire real-life relationship was that they just had sex once...

Then we know that he disappeared on Becca for a while after she drowned herself to be with him, so what was that?.. She specifically mentioned btw that it was a week, but he said in a prior scene with the fur coat that he had no perception of time anymore. I don't know, I may be answering my own question with this. The only thing that's inconsistent was why Becca thought it was a week.

Then also the thing with the body swap with the kids - I don't know what to make of that either. His intention was for his and Becca's spirits as adult lovers to move into these two kids who are siblings?? How would that have worked, exactly?

Oh, and then it was he who killed Hannah, correct? That is definitely at odds with the decent guy he comes across as in the scenes with his abomination of a mother.

Anyway, kudos on the performance, Oliver Jackson-Cohen, you beautiful, beautiful man!
