I think tulika put something in Anu's coffee to make her throw or give her some stomache pains so she think it's the baby and everyone will find out that she's pregnant and Anuj will find out be sad then say I'll marry anu since know else will cuz she's pregnant.
i think she put something in it to make anu drowsy so that she will be seen with anuj and everyone will think they did something- so they have to get married- at least that's what it seems like from the preview!
i think she mixed some sleepy powder so anu will somehow end up with anuj!! to make anu look bad i guess!! so she will try to make them to get married cuz everyone will think them two slept together!! and anu is already pregnant, so they might think that its anuj's baby!!
