Ok first, i actually liked today's episode- just watched now because after reading updates i decided not to watch but i did and glad that i did.. the only issue i have with episode is that bill and money control scene..otherwise for the very first time i liked sunkee's scene too - after raghvi's marriage track may be first time i liked kirti's acting or may be its this baby track that caught my attention🤷♀️ don't know but for today i liked their scenes and didn't ff😅😅 and raghav pallavi with farhad is just "the best trio" in this show- whenever they three comes together, they nailed it❤️
Now coming to main point about Ex track,, may be i am in odd numbers but i am really liking the build up and looking forward for this track..
See in Mandar's case Pallavi never loved him but belived that he's a good man(that's what she said) so even when he came there was no romantic angle but psycho angle..where here the whole thing is different because Raghav and Isha was in a proper love relationship and planned to marry(according to audio recording) but for some reasons it didn't happen(we will ofcourse get to know the reasons) and as i was telling yesterday only that we will get some flashbacks or indicative dialogues to understand how close they were...and that's pretty normal for people who were/are in love - i mean let's be honest, how many of us still remember the first crush or first love of our life which didn't end the way we wanted? But sometimes - once in a blue moon it just pop up in our mind and all memories/flashbacks just comes together- sometimes it feel good - not in romantic way but like how we used be before and sometimes it just gives us pain - like how it ended💔
I am telling you this by my personal experience..we don't - actually we can't hate that very person whom we used to love so much- time passes and we just move on with our life and that thing already happened with Raghav.. no matter how he smiled on remembering Isha but the reality is Pallavi - We all know how much he loves her so not to worry from his side..
Now why this track is needed?
First ofcourse - TRP,,, second - Many fans demanded this..third - see we all love pallavi but in some matters she does overdo and we all know it like today that money thing and marriage is not a sudharofy constitution,,,its more about accept your partner the way he/she is and then make them understand in a different way so for her character growth also i think this one is important because she has never felt that insecurity of losing him and that's why may be she sometimes go overboard or take him for granted - just sometimes... 
So i am really looking forward to watch this track -may be the sadistic in me is also excited- just really hope makers execute this with much maturity and sensibility and ofcourse rajdhani na bhagaye.. :)
Feel free to disagree 😅 because i know many are not happy with this track..
