My thoughts...............
The foreshadowing
1) bajaj saying he don't talk to people who accuse him like that. With all these villains and anurag creating problems in bajaj and prerna relationship I believe we may see prerna doubting bajaj and accusing him. However she will find out the truth herself.
2) bajaj saying that anurag doing the deal with the London investors will possibly bring his own downfall which it will and the fault will be on bajaj most likely. But not worried for bajaj. He doesn't care who accuses him or not. Also prerna will find out one way or another that it wasn't bajaj. We might get frustrating scenes before she does though.
3) bajaj not accepting prerna help. Bajaj is reluctant to get close to prerna because of his past. His ex wife hurt him badly so he is trying to not get close to prerna. He fears what will happen if he let prerna into his life. However that is the only thing that will be beyond his control because prerna care and respect for him will turn him.
4) prerna saying she will leave the house with bajaj if anurag crosses his limits. I've said this is foreshadowing. Anurag is playing dirty and he wouldn't miss a chance to ruin bajaj and blame things on him. Anurag will do something that will make prerna upset and leave.
