The raaz

so this is my take or atleast if I was writing the story this is how I would take the story forward

The whole raaz they played today, the cd is doctored.

Why I think that?
The strong conjecture has been that the raaz is related to anika and her past. Yet anika didn't show any signs of recognition of the person.
If tej knew for sure it had proof of his crime (for s crime has definitely been committed)then he wouldn't have let that video being played at all.
When the video started shaktis reaction indicated that he doesn't know that girl and that the video is bullshit(though initially he was nervous for there is something somewhere for sure)

So this is my take - gayathri intended to get caught,she had the doctored cd and intentionally flaunted it so it will be caught, alerter the police herself so that an investigation can be started. I think her main aim was to get investigation started snd she achieved that and hence the creepy smile towards the end.

Coming to the raaz - something similar must have happened. Don't think shakti and tej Would have intended to kill someone but they may have been the reason for anikas parents death and separation from her sis.

Coming to ishana - it seems stupid to think that the raaz is common knowledge that ishana made a statement like that. Unless ishana is the sis and she remembers some part of the incident and seeing or hearing tej's name and hence the very strong statement from her. This way they can redeem her character that though they initially showed her as wanting to do this simply for money that it wasn't just money but revenge. She knows that the reason behind her family breaking up are the oberois and that's why she was so intent on entering omkatas life. She has been keeping an eye on them all the whole and waiting for the right time to strike. And her dard
Se rishta also makes sense if it has a bigger backstory than just her being poor and therefore dard se rishta.

There my be some reason that Anika is unaware of obros being the cause for their family's situation. Maybe she was out of town or school trip some such stuff.

So I think Anika will try to find out truth about gayathri in order to help shivaay and his family. And during that process she will find out her own truth and then starts the revenge of the sisters! (Either together if they get United or separately and later they come to know about each other!)

This can keep the tension high between the romantic leads and also build strong characters, test the brothers and their strength because the first thing both sis will attack is their unity!!!

I agree with you.

I agree with you.

But still they we see that the CD was take from the locker.

Even if it was a plot by the lady. How does the recording got saved.

After the girl killed herelf, from where the hell the video got saved and came into oberoi mansion ka locker. Did he CD himself felt that he should protect he oberois!

The cd was never in the locker. Gayathri had it with her when she came in. She did the whole drama and intentionally got caught to show the cd and make it seem like she took it from the locker. But she must have had it all along! If she had the code and opened the locker herself why would the alarm go off? Unless she pressed the alarm herself!
