Now that I'm looking at the revised schedule, the Sam event for the afternoon is right between two Dylan events. I wonder if that might not somehow tie into one another, like Sophia has some interaction with Dylan, then leaves to do a cello lesson with Sam, and Dylan stealthily follows, and ends up witnessing Sophia and Sam doing something intimate (we're owed a BJ at this point), and then the third segment would be a POV where you as Dylan decide how you want to process this information (confront them/act like you didn't see anything), and then Dylan gets his revenge by banging Sam's mom, which will be the first major hetero scene.
I'm on to you, L&P.
