I think its funny, that rashi's and kaya's roles are reversed. Rashi plays negative in KAA and in KS she is positve and totally different. Kaya is a sweet heart in KAA and as Ablisha in KS a negative. Its neat to see two different sides of the spectrum!
What else.....I think the child is jai's and the mystery man is Sahil because he was giving his kid to ablisha's dad. Maybe Sahil is poisoning Rashi and Rashi isn't even sick with cancer. Maybe Sahil wants to get rid of all the people that support Bani like Rashi, Adiyta and now Ranveer. Sahil was asking Ranveer for his support during the project thing but Ranveer, flat down denined him done and said he supports Bani. I think he was going to kill adyita becasue well adyita always supports bani and during the voting he was with bani instead of supporting his own son. I think it was a hoax that that guy was trying to kill him. He knows how much rano loves him and she would save him and while saving she would kill the baby. He did this because he wanted the baby to be aborted, remember and then he finds out that the baby surives, he decides to get rid of it through Ablisha's dad. So, now bad Sahil, knows bani's Bond girl behaviour and her determination to get the truth. He knew she would follow and thus kidnaps her and he also knew Jai would follow and now kidnaps him too! So sahil is now trying to get rid of the two love birds from the picture.
I think I am reading toooo much into this, but this is the only way I can make sense of the retardedness of the show.
