Yes, it's a huge stretch. I get that since the start of episode 2 the story has been leaning pretty heavily towards the afore mentioned nonesensical character destroying farce path. But even then ...
Ellie and Sophia getting hot and heavy in front of a couple of college underclassmen, one of which we know Sophia doesn't like, doesn't make any sense at all. Correct me if I'm wrong, but I believe the only way this scene even happens is if Ellie forgave Logan, meaning they are still a couple. Sophia doesn't like Logan, and certainly not as a partner for Ellie. There is zero incentive for Sophia to do anything that would keep Logan interested in Ellie or think that there's some Ellie/Sophia sharing option for him in the future.
Also, Sophia is not going to cheat on her husband in front of her daughter, unless we're truly and irredeemably on the path to the dark side of the farce.
So I think we're left with either dumb, or rehash, or, and most probably, dumb rehash.
First of all - I agree with you!
The initial situation/initial conditions do not actually allow anything sexual to be possible in the presence or even with the involvement of Logan and Tyler. This is especially true if Sophia spent the night before with Dylan and is full of regret.
But considering the third and fourth teasers, which show what L&P described as "a playful Sophia", it seems to me that the only difference in this upcoming update will be at what point Sophia accepts her "inner whore".
Immediately after getting up or later when she is/was at the spa with Ellie.
This is the only way to even explain any progress or interactions with the two men at this point.
If L&P chooses this route to explain Sophia then the story becomes even stranger when L&P then has Sophia have a "serious" conversation with Dylan about the events of the previous day. Because this conversation will come and if L&P actually lets Sophia act as suggested in the text above, it will be contradictory and hilarious and will make any form of "believable" ridiculous.
One should also take into account an early statement from L&P. When Aiden's blackmail of Sophia began and Dylan was the perpetrator of this blackmail, and it was hotly debated, L&P once said that at some point it will no longer matter that it is blackmail and who is to blame. If you take this statement into account then you can understand that this weekend should lead to a profound change in behavior for Sophai.
At least that's how L&P could imagine it.
So far we only know individual images of the upcoming update. And of course everyone here tries to give an interpretation to these images and, based on past events, together with their own ideas and wishes, to predict how the update will develop. I also don't want to judge L&P too harshly at this point until the new update has been released. But at the moment I see that we're going to get something very erotic and sexual, but in terms of the story it could be a catastrophe.
But maybe L&P has an idea up its sleeve and will surprise me.
That is the goal, especially for a game with a "corruption" tag.
