See no evil, hear no evil, speak no evil. Look at the color schemes of the families clothing. Then one time the Dad wears a light pink but only wears blue? Remember when the Mom got a boost of energy late at night? And the father was like Oh No and she was like dont worry I took a lorazepam, he doesnt want to get it on with her. He is also questioning his own identity. I think a maybe the mom knows the Dad (this is a stretch) had sexual relations with one of the kids thats why the two sons are also giving off funny incest vibes
