I’m sorry, but what sort of father, after his daughter comes to him traumatized (so affrighted!) decides to go talk to his boss? His first thought is to take his trembling daughter to the King? This would benefit Ophelia how? Seems to me that this would benefit Polonius himself in giving him an in with Claudius. He’ll give him the paternal impulse to do something first. Many a father might want to spring into action in response to a crying daughter. But to the king? I don’t know about that. The fathers I know would be more inclined to go have some words with the man who made their daughters cry. They’d go talk to Hamlet himself if they were concerned with their girls. The king? Ophelia never seems more of a pawn in his game than here. Does he deserve her devotion? Her subsequent madness?
