Like Travaruz said, Alice probably spilled coffee over her and now they are together in the bathroom,my guess is that David and Sarah will go there to have some fun and both, Alice and Silvia, will hear them and find out the truth... if you think about it, Uncle Peter already know, Aaron already know, makes sense Alice is next.
Also, I insist that Silvia will be Sharon's mom, if Daval make her watch an aunt and nephew having sex, she may try it with Daniel in ID, I know some people don't want to see Daniel with other girls, but this is a porn comic, I'm sure Daval will give Daniel an harem, Lana will always be the main one tho! but I would not mind at all a threesome between Daniel, Lana and Silvia, would be way hotter than Liam, Amanda and Alexa...
