When veena interrupted Sinal and took siddhi to dining place and forcing her to eat kheer. At start, i felt so horrible. I love to watch kunal enjoying the kheer scene. His smile and teasing dialogues to siddhi. It was so goood. Before his entry, the scene and moods were so serious. The moment he entered, the whole situation became so light and lovable. He was not angry on his mother, as well... he totally avoided the topic from anand to kheer and kismiss... His entry made veena to stop talking anand jaap and siddhi fully in trance of his provoking dialogues. So that, siddhi can be taken care very well by veena, meanwhile unnecessary dialogues between them can be avoided with kunal presence and interference.
Actually this is the way i want him to treat siddhi whenever veena interrupts them, so that she wont be more depressed by veena's behaviour. Make the moment lighter by interfering between them without hurting anyone. It is happening exactly how want to see.
