Yea but the whole thing about Star convincing herself she liked Oskar while in front of HER MOTHER parallels to that whole chat with Marco and his FATHER. Do you see what they're doing here? They're both in denial. That's why Marco's dad refers to Star has his partner in crime, and why his parents look at each other knowingly once Star confesses. I know that seems crazy but Marco is literally retarded with his own feelings. I really don't even think he truly understands the scope of what Star means to him, and like I said many times before, Star leaving will finally make him realize it. He's going to be devastated. Look at his face when he sees her room disappear.
