Just watched the episode and I happen to really like the scenes with Kunal fighting with his emotions and on the other hand Siddhi fighting with hers. Kunal standing aloof and sad, in so much pain just knowing that Siddhi was moving on in life. Seema tried to knock sense into him but his question of why he couldn't move on if Siddhi could. It is more of a competition for him to prove that he has moved on, just like Siddhi supposedly has. He wants to convince himself that what he is doing is right, but he is just failing.... And after Seema pointed out to him that he was jealous, he wanted to make sure he hid his jealousy. But trying to suppress your emotions and feelings does nothing but bring it to the surface again and again. Similarly, for Siddhi, the way Siddhi felt bad for sending Kunal away and then saying how she constantly thought of him. The way she threw his shirt thinking that she should not have such feelings for a married man but then not being able to hold herself back and holding the shirt just to feel Kunal close to her. There was so much longing in her eyes... She is trying to hold back as much as Kunal is but is failing to the same extent. She can say as many hurtful things as he can, yet she can't help herself from wanting to be with him.
They both are fighting constantly and fighting so hard to let go, to not think about each other, to hate each other, to move on from each other but putting their thoughts into actions seems harder than they can imagine. Both "think" there are certain boundaries in their current relationship which they cannot cross but time after time, they BOTH cross these boundaries with their actions, then try to pull back and eventually end up in an emotional turmoil. Even in the last scene, Siddhi looks at Kunal and puts her longing for him into words by saying she would want to give her life and herself a second chance, Kunal walks in and speaks at the very moment he thinks Abhay is going to propose Siddhi. Directly or indirectly, explicitly or implicitly, they both are failing miserably to keep their feelings for each other in check and that is being portrayed very well onscreen. Good going on whoever wrote the screenplay for these Kunal Siddhi scenes. Their constant battle with their love for each other along with the hurt, the pain, the pining, and the inability to just hold back, it came across beautifully in the two scenes. The separation was stupid and unjustified but the journey to the reunion is being paved beautifully, well atleast for now it is.
