But we all knew about Chad's secret. There were some discussions on reddit about who was chad's affair and I pointed a few situations that made me think he was gay and other people figured it was mc's roomate Roy, even saying he is probably melanie's brother and that is why she protects their relationship. At the end we were right. He is gay and his relationship is with Roy. So that wasn't a surprise for us. But Sage is. I think it is funny though because in past episodes they showed Jade's family pictures and Sage wasn't in it, so maybe DPC, instead of adding new characters, decided to use the ones that already exists. It is important to talk about what sage tells at the reps party on Ep. 5. The way she described her dad's business sounds like he is an investor and he wants her to follow his steps. What makes no sense imo, if He is the college's director.
He is also ok with his adopted daughter being the president of HoTs. That he knows about the prostitution and yet use their services.
In other hand, I remember Chad asking her for help when he got kicked from the Alphas. And she saying no to him. He probably knows that she is the Dean's daughter.
