You presume Jill accepts that she has an unconscious sleep humping problem. That seems like the sort of thing she might be embarrassed about and would insist to herself won't happen again... especially if she has incomplete evidence that it very well might. Which, incidentally, is pretty much exactly how that scene plays out: Bella doesn't trust Jill's word but doesn't want to call her out, Jill takes umbrage at the implication.
If she brings it up then there must be some level of acceptance that it happened, and even if she believes it wouldn't happen again, she's aware and conscious enough of it that she was going to sleep on the couch. If she was concerned enough to consider doing that for a friend, then why would she allow the MC, someone she is still getting to know, to sleep in the same bed with her if she has these concerns about doing something in her sleep?
This is why I don't see it being the sleep humping because if she's concerned about it here then she would have been concerned about it in Ep 3, but she wasn't. Also, Bella is seemingly the most uncomfortable with this line of conversation which would suggest that she feels most guilty about it and wants to avoid talking about it. If Jill had been sleep humping, surely she'd be the one who feels most guilty.
As for pushing James' picture, it's a good question either way. If Bella did something with Jill that caused problems with James... why would she metaphorically take this out on James now? Why knock his picture to the ground if she's feeling guilty about what she did to him? We know Bella wants James to come back, so it seems odd she would slap the wedding picture that way.
Meanwhile, if whatever Jill is reminding her of is of something James did to her, how would that fit Jill's dialog about it not happening again? Or, if Bella just reacts negatively to being reminded of her sexuality and/or failed marriage, why didn't the MC's drunken kiss result in a similar outburst?
The Bella/Jill theory, I feel, has a good answer as to how James relates to this:
If he cheated on Bella but they stayed together to work on their issues, then their relationship would be quite fractious as they go through this. Continuous arguments, tension, acrimony, etc, could have led to frustration and feelings of depression/dejection/heartbreak within Bella. Add Jill to the mixture who's going through the same thing, throw in some alcohol to loosen them up, and maybe they went a step too far in seeking physical comfort, and James entered and witnessed it. Bella would, of course, blame herself for doing this with a friend, but also blame James because if not for the problems he caused, it never would have happened.
in fact Jill was so excited and intoxicated by the wine that 5 minutes later with MC she doesn't let go at all, and stops him after a kiss.
Because the MC doesn't resist it. Jill eventually comes to her senses before it goes too far, but if a similar tension was building between Bella and Jill, Bella realised early enough to stop it, but the MC did not wish to stop it.
if there were ever these difficulties between them, they would not hang out on a daily basis
That is patently false. People can still be friends after an incident like that, it doesn't mean they have to stop being friends.
I would suggest that most don't share intimate details of their love life with mere colleagues, let alone bring them into the marital bedroom. That level of trust implies a deeper relationship to me (i.e. friends+), particularly given Bella's reserved demeanor. Surely mere colleagues wouldn't expect Bella to be up for it, she hardly screams swinger right? I don't think professional courtesy covers swinging either...
As you mentioned in a previous post, they were still close enough for Stephen & Jade to invite Bella to dinner in Ep 1, so hadn't fallen out yet:
They were chummy in Ep1, things went pear shaped after that. I imagine the proposition happened at said dinner, which fits the timeline of the events being discussed.
Sometimes people can confuse/misunderstand a working relationship for something more. I'm sure there are many people out there who think of their work colleagues as "friends", but their colleagues do not.
Person #1: "But I thought we were friends?"
Person #2: "No, we just work together."
Stephen certainly seems like the type of person to think that Bella is their friend, and Bella certainly seems like the type of person to not think that.
Also, given Stephen's high position in the college (whatever that is), Bella could easily assume that this is a working dinner, to discuss things about the college, the library, her position as a teacher, etc. A dinner invite doesn't have to mean that people are friends as it can be simply professional in nature in a situation like this.
We don't know, we don't need to know for the scene to work. Some interpret the looks to hint at underlying sexual tension, I don't see any of that. Bella is cross, Jill is concerned then offended. Anything beyond that is baseless speculation imo. I've offered alternative explanations for why they may have argued which are as plausible, if not more so, than the Bella/Jill thing, but they are also conjecture.
Bella becomes cross when Jill brings up a past incident. When she turns from her it seems like she's trying to avoid something, not that she is cross with Jill.
Jill wants to leave the room because they're arguing, it neither offers nor needs an explanation beyond that.
Yes, she does, but prior to that she said she was planning to sleep on the couch had it not been for the MC staying over. So clearly Jill knew it wasn't advisable to sleep in the same bed and that's curious. Why would she think that it's not a good idea, and why does it seem to relate to a past incident that would seem to have involved the 2 of them?
I consider the entire concept of the Bella/Jill thing as completely at odds with their characters as presented so far & would be astounded if that were the case.
What's been presented of Bella and Jill is very little at this stage. We have some small pieces of information here and there, but not yet enough to build a complete picture of who they are. So really, I think it's easily and entirely possible that it could be written this way and I think it would work just fine and wouldn't be damaging to their characters. If it isn't, well then fair enough, but I don't see it as a problem if it were.
Don't bother, user is clearly a troll. Didn't even attempt to respond when I directed him to the walkthrough in the OP post and continues to complain about the free roams for pages on end.
The free-roams are easy when using the walkthrough, but they're also easy without it. For as much flack as the Prep mansion free-roam got in Ep 5, it was easy to figure out what needed to be done by exploring every room and paying attention to the dialogue.
If they can't figure their way out of these free-roams, then they must be very bad at this sort of thing.
