That was after v0.150, so we assumed that "the within the next 3 PDs" means PD 15 is the last PD where it can happen (among PDs 13, 14 and 15). That's why the hints suggest the ranch event on PD 15.
That being said, I agree that at the moment it's difficult to imagine Sophia/Patricia given the progression they had so far. There is still the museum event to have some progress, even though we know it won't be a lesbian oriented event. The only explanation would be that the event will be big (read "long") enough to have a big progress leading to the scene.
