Kat's Analysis (and brick-bats are allowed 😉):
When ArYa returned from the infamous hotel and Radha was going on and on about Arti being the greatest mom, she got Ayu back and deserves to - the predominant look on Arti's face was that of guilt. At one point, if i am not mistaken she turns to look at Pari during this glorification speech. The way i read the situation - Arti realized at that point the pain she was going to inflict on Pari - the same pain she had suffered through for so many weeks. And so - the guilt. The guilt of a mother who knows the almost debilitating pain of losing a child, about to give that same pain to another mother.
Then when Pari comes down and gives her mini-speech, the pain Arti feared she would see was there (btw - Leena did this scene really well. Another actor who has grown during this show). Pari may be a selfish, childish woman - but she is basically a very decent and honest person. What we say in Hindi - dil mein kuch nahi rakhti. The one person in that family who calls a spade a spade. So her pain was visible - and audible. And Arti picked up on it.
Now to the point of contention - Arti "giving" the child to Pari. Did she? I mean really? Legally yes, she stated Ayu will be Pratik and Pari's child. But he will be growing up in this family, where everyone knows what the deal is. I see multiple things playing a role here:
1. Arti is instinctive. And when she follows her instincts, she rarely if ever is wrong.
2. Pari may not have given birth to the baby, but that does not mean she is not attached to him. She felt the pangs of not being able to conceive for a while. She felt them strongly enough that she yearned for a baby of her own - which led her to adopt going against her husband's wishes. So when she got the baby finally she would have felt a surge of mamta, a strong protective and possessive emotion.
3. True, Pari is not a skilled mother. Which first time mother is? And most women get a few months to prepare themselves - and are still woefully inadequate once the child is born. Pari is learning on the fly - and it takes time. There was criticism about her not knowing Ayu was sick. Umm, news flash - many first time moms don't realize either. I remember when my SIL came with her baby (who was older than Ayu here - so she had already had a few months with him) i told her he was sickening - and she called me the next morning asking what to do because he did fall sick enough for the new, first-time parents to realize. Happens - to all of us.
4. Pari and Pratik are childish. Yes they are - its their charm and their curse. But they have never really had a chance to grow and mature. Having a child to love, care for and be responsible for is already making them grow-up. See Pratik's explanation and Pari's reaction - neither would have been able to act the way they did one year ago.
5. Arti and Yash are not giving up Ayu. They will be the ever-present omniscient mother and father-figure. Arti will still take care of Ayu - and this time Pari will not question it. And neither is Pari in a position to resent it anymore. In many ways, Arti has left Pari helpless here - she has given up her child to the other couple, but only legally. Emotionally, she is just as vested in him - and Pari recognizes that.
6. Arti did not consult Yash - true, but that is probably due to the show ending and GC's availability. If you want to see from the story point-of-view: Yash knew she would do that when Pari started her speech - at that instant, Yash knew Arti's final reaction. These two have come a long way and have understood each other well enough for him to predict his wife's action, accept it without discussion, and for her to make that decision for them as a couple.
And finally - how real is it? Ah - its a show. We accept things in fiction that are beyond our tolerance level in real life. Would i ever give up my child? Heck no (and i have four - somedays i tell you...). Did i expect Arti to? Yes - totally in character and fitting in with the show. It would have been interesting to see how this "act" of hers plays out over the years...But then so many things would have been just as interesting with these two wonderful characters.
And can i just end with - i loved KS in this episode. Its difficult to believe she is not a mother in real life because she portrayed a mother's guilt, her angst, her pain, her torturous indecsion, her conflicting mamta so very beautifully...Kratika, i will miss you.
