It looks like my assumption that Sophia would not rush to Sam with flying colors was correct. It's no surprise that she wants to talk to Sam. She wants to bring this relationship back to normal. She's troubled by the events and her own behavior the day before in the hot tub, and I think Sophia considers her behavior unforgivable.
Sam is going to have to work hard to convince Sophia to allow the relationship to progress. But since we already know this event is going to be "hot", Sam will be able to pull it off. I'm not making any predictions about how L&P will shape the dialogue, but the silver-tongued Sam will surely talk Sophia's brains out. But actually he should have no chance without alcohol.
I also have to agree with Sam's fans, this event will catapult Sam way ahead of Dylan in Sophia's favor. If Sophia gives herself to Sam again, becomes sexually active with him, that is not possible without Sophia having to admit to herself that she wants to (unless she is massively under the influence of alcohol). She must admit to herself that she is deliberately deceiving her husband, Liam. The game with her dreams now becomes an affair with intent. And so Sam is far ahead of Dylan in the race for this woman.
But this race doesn't really matter. Because when she meets Dylan afterwards, and spends the rest of the afternoon with him, it will be as if the meeting with Sam never happened (L&P will keep the routes nice and separate.).
I don't dare predict how the whole thing will play out, nor how far the sexual acts with Sam will go. But I do make one prediction: the events will not reconcile the Sam fans and the Sam opponents, but will further tear open the rifts.
