I also was thinking it was going to end.
However I am thinking maybe it's being set up for the new storyline which is the children. We have three unsolved problems at this time
1. The retrieval of Saloni's daughter
2. Tara's possessiveness
3. Kaveri/Samar/Ginni storyline
What ended yesterday was Kalika's revenge and the reunion of Narpat/Ambika storyline.
However, in yesterday's episode although Tara was 'repentant' she has not changed. It was clear her asking for forgiveness was reminicent of her asking for forgiveness from Saloni after Saloni lost her child and came out of her shock. So, we can make the assumption that she is still the clingy mother she always was and will be. So I am assuming that her child is going to be a spoilt mother's boy, which spells gloom and doom for that family.
I don't believe that NS will be looking for their child long, the child is dark. So it's going to face some serious prejudice.
In the case of Ginni/Samar/Kaveri, we know that Ginni is in Samar's and Nikita life to stay whether he gets back with Kaveri or not but it does mean that Kaveri's child is going to resent Nikita. Kaveri is going to poison that child mind.
