Laksh and KT are not getting married guys that is just final. It was never going to happen guys. Ekta is never going to let that happen. I am also 100000% sure that KT will get pregnant, but I am also sure that Tulsi will not ask KT to marry Mayank.
What is going to happen is Eku is going to turn evil. Eventually the truth about Mayank will come out, but that wont change eku because they still blamed him and he will still be pissed. KT will get pregnant, Tripti for sure this time will not get crossed and she will win, and KT will refuse to marry Laksh. Meanwhile Mayank will play all innocent and pretend like he is sick and that he will marry KT and take good care of her. Tulsi could melt with this gesture and realize that maybe it is for the best. But I dont think that will happen either, since eku is still evil, I still feel that he will refuse to marry KT to his brother, and will think KT is not good enough for his brother. Ofcourse eku will not realize that his brother is just playing games with everyone. But Tulsi and Damini will push for this wedding, KT will eventually accept Mayank thinking he is just a child and she can take care of him. Something could happen to mayank at this stage, ekta can make him disappear before the wedding, eku himself plots the kidnapping of his brother mayank, I think KT will be left stranded and pregnant, and I think eklavya will offer to marry KT just for revenge.
Mayank will make an reappearance, Mayank is bloody furious, but eku thinks he did what was best for his brother. But I think eku will find out the truth about his brother's real mentality. Eku will probably come out of his bad temper phase and realize that maybe it is time to change again. just when KT and eku are starting to like each other again. Mayank will start to play games, he will spill the beans saying eku kidnapped him before the wedding and he wanted to marry kt all along. eku will be stuck he knows his brother is just evil, he will genuinely want to help kt, but no one will believe him again, misunderstandings happen and there is a lot of drama.
