I double checked, and fine, he has seen Sophia's panties. Aiden now has as well. I do occasionally make mistakes, particularly on scenes I've never played. I haven't even played the scene in the seafood restaurant. But he's still trailing characters like Zac and Emma.
My point was simply that the people that complain about the lack of progress of characters all seem to play the blackmail route and only the blackmail route. That see Sophia as a weak, manipulable plaything and believe that's all there is to the game. But if you see Sophia as a strong, independent, intelligent woman, there are plenty of routes with more content that what the detractors complain the game is limited to. Even without playing the incest route.
But yeah, as always, if you support the game, enjoy it as you please. I can't stop you. Criticise the game though with a BS excuse like "we haven't seen Sophia naked", which hasn't been true since day 11, and I'm going to slam it down.
