I think KTH is more all about Sujal-Kashish than about 5 sisters. But yes, Sujal will not marry Gayatri, even if he does it will be to ruin the ahluwalias. That is option 1.
The 2nd option which I think will actually happen, is that he will find out the truth about Kashish's marriage to Bauji and his hatred/anger will cool off. After today's episode its clear that he needed to be jolted. Thanks to Mouli. Good girl. But I pity her as I think Siddharth is the killer!!!😭
Anyway the whole serial is in a mess. And there is still Sameer to come, Ekta is introducing some new character for Gayatri. Ooooofff. What a long tedious wait for the union of Sujal-Kashish.
Does anyone agree to what I have commented?
