There was absolutely no artifice in the way he said that, there was complete conviction. Two things became clear from this. Firstly for those fearing (and some even hoping!!) that he would turn negative, there seems to be almost nil chances of that now, the way his thoughts and actions are coming across . (I say almost nil, since nothing is impossible in serial land, after all...).
But the second, and IMO, the major thing this snippet of dialogue achieved, was to put the whole "drunken tent burning and love confession" scene, in perspective, before it airs.
When the spoilers first came out of that scene, frankly I was a little disappointed. I was like "Yaar yeh zyada filmi ho gaya" 😊 But now that I think back to this dialogue of Sanskaar's yesterday, it actually makes sense, that he would confess this way--indeed, this was probably the only way he could have let his feelings slip out.
Already, he is battling the demons of losing Kavita, his wounds have just started healing now that Swara has entered his life. This would have made it hard anyway, for him to accept his changed emotions for Swara, but he is facing even bigger demons--that of his own initial complicity in putting Swara in this position. Though he could well console himself that he is standing by Swara like a rock now, I think Sanskaar's guilt and remorse go too deep for him to judge himself as worthy of her love.
Thinking it over again, I felt there was possibly very little chance of Sanskaar actually assertively telling Swara, while in full control of his senses, that he loved her. In all likelihood, he himself is too reluctant to acknowledge these feelings in his conscious thoughts.
Albeit in a drunken haze, his confession is probably all the more poignant, since it reveals the depth of his emotion in his subconscious. Hope Swara realizes that, and starts reciprocating soon. 😊
