That is right, Gardes.
During the bathroom scene when the clarification was made, I knew it is going to backfire - the unusual way she teaches things to him.
I'm not saying it is Runjhun's fault, but I will blame the circumstances for it. If Kalsanwali hadn't played with the food, this spat between them wouldn't have happened.
His temper mercurially raised bcos of what he had "learned" just that morning. Even the night before and in the morning before the bath he says to her that, "she is very intelligent .. very smart". In the night it was said with bitterness, and in the morning it was said with a bit of appreciation. When the clarification was made in the bathroom scene, he got to see her intelligence one more time and he takes it that she is teaching him again something bcos of the mobile- company-offer issue.
Also just before eating he advices K & J to respect "AnnaDevta" and eat .. and what he did was totally against what he had just said minutes before.
So, for a person who has the knowledge that 'Food should be respect' behaves that way, how much it must have angered him is what was being shown.
For the records, this is the 3rd time he is telling her that she is taking "revenge" on him. He who has lived an outside life all the time, only knows such tactics.
Like I wrote in a WU a while back, in the precap. it is Runjhun who is crying away with tears flowing from both her eyes, but it is someone else melting in those tears - GUDDU! You can see in his expressions ..how he is totally M.E.L.T.I.N.G
Looks like with each of the tests, they will get closer and closer forming a strong bond of trust with each other.
