What if the restaurant is something completely different than we previously thought and Sage knows about everything because she is managing it herself in the background.
What kind of codes does Quinn mean and why does Sage intervene here to silence Quinn? It seems to be important to Sage that the MC doesn't find out about it. Most importantly, Quinn is talking about codes (plural).
Might it have something to do with the blindfold? Sage thinks it's funny. Maybe a code is for HOTs to check out their sisters' future boyfriends to see if they are faithful, gay, horny dogs, etc.
Elena says before the party planning at the Dorm party so she thinks so Josy and the MC love each other. She knows this because Josy always beams when the MC's name is mentioned. John, on the other hand, thinks that the MC is a player. What if the blindfold game is the game John meant. Is this a HOTs test to see if the MC stays faithful to Josy and Maya or plays around with other girls?
However, it takes sisters and brothers to cross boundaries. Is this perhaps the secret of the restaurant. Did Quinn maybe think Maya was one of those sisters who crosses boundaries? I mean, she looks really sexy in EP1. Do the HOTs and the DIKs even do this commercially to convict unfaithful partners?
