If I recall correctly, the “ Ellie ” route is supposed to split in the future.I look at it like this in order to keep things in perspective: do you think Sophia is one week away from having sex with her daughter? My answer is "no". I agree with you that Ellie is in the lead right now (putting aside Liam), but I don't think Sophia is a week away from having sex with her. Now, the time jump could change this depending on how long it is, but for simplicity let's ignore the upcoming time jump. In a normal affair, the person is at least contemplating the idea a week out from when the actual affair begins. And while Sophia has crossed some lines with Ellie, she hasn't expressed an interest in having sex with Ellie yet.
HOWEVER, I have a theory because you're right that if they have sex the next question is does the relationship get blown wide open. My theory is that Logan (and Patricia to a lesser extent) will play a critical role in Sophia and Ellie expanding their relationship. While I don't think that Ellie and Sophia will necessarily have a threesome with Logan, I do think it will be something close to that. I see a scenario where Ellie and Logan are hanging out (maybe as a group, maybe just the two of them) and for some reason Sophia is there as well. Since Logan only knows Sophia to be Ellie's "friend", I can see a scenario where Ellie and Sophia are challenged by Logan to make-out (or more). The player will have the choice to refuse and expose Sophia as Ellie's mother, or play along in order to maintain the ruse.
My theory leaves a lot of questions unanswered, but I think it's a plausible way for Sophia and Ellie to move forward. I think such a scenario would give the two of them the cover they still need to act on the feelings they have but are trying to suppress. So far when Ellie and Sophia have had sexual encounters in the shower, it's always been under the guise of teaching/showing Ellie. This gives Sophia the cover she needs to do something that she wants but that she knows she SHOULDN'T want. In the case of a threeway kiss/whatever with Logan, it would be the same idea. "Oh, I shouldn't do this but I want to keep my cover in one piece, so I guess I'll just make-out with my daughter and maybe Logan at the same time. And if my hands wander, well that's just me pretending that I'm enjoying this."
I can see the scenario with Logan happening in the “bitch Ellie route ” ( I’m not calling it like that to insult Ellie in case someone is wondering, it’s just that if you make certain decisions in the game, you end up with some “bitch Ellie ” points.
But on a strict Ellie/Sophia relationship I don’t know where L&p is going.
Does they fall so in love with each other that they leave Liam and Dylan and go live together happily ever after ?
I know that many people would enjoy that type of ending but I would like to have some semblance of realism and not have an nice ending just for the heck of it.
And again, for those who don’t understand, I’m not saying that it’s bad that Ellie has made that much progress or that I would prefer other characters to be ahead of her.
It’s just that she’s still her daughter at the end of the day.
Dylan is in the same case being her son, but he is far from where Ellie is at the moment.
