Ghar ke Laxmi Betiyaan on Zee - the return of Pavitraa

Today was a strange episode of this serial. So soon after Pavitraa was literally made an outcast, she is again brought back into the mainstream of the serial. Yuvraj had met this pretty girl called Niyati, and married her. She settled very fast into the family, and started getting along very well with the others (and this was inspite of Pavitraa trying to kidnap her to keep her away from the marriage). Soon after, Niyati declared that she was pregnant, and lo and behold, everybody started to anticipate the heir to the household. Pavitraa could not stand any of this and she started plotting how to get rid of Niyati. And she finally managed to get Niyati out of the house and into the open, and of course an accident was bound to happen.
The accident killed Niyati's child and also left her unable to conceive again; and this was a killer for the household - where would the heir come from ? And of course, Pavitraa has a baby growing in her from the time when she was with Yuvraj, and she is ready to become the heir generating mother for the household. Except for Menaka and Niyati (why does the daughter in law always out of guilt agree to such things ? There are so many other options available nowadays as IVF, surrogate mothership and so on), everybody else is against this. However, you know what will happen. Kavitraa comes back to the household, all ready to do her manipulation again.
In a side drama, Menaka is getting blackmailed by her own brother, who finally reveals that Yuvraj is not her son; Menaka in fact gave birth to a son. If this is the case and this gets revealed, this will be a massive shock to the entire household and change Menaka's position in the household.

Kahaani Ghar Ghar Kii - the murder mystery

Balaji serials have the unique ability to spin a murder mystery into a long and complicated hunt with one common characteristic - at one point, all the characters have become suspected of the murder before they are one after the other proved innocent. And so it is starting to happen in Kahaani Ghar Ghar Ki. Consider the scenario.
The wayward daughter of the house, Tanu, becomes more and more rebellious, and soon after the real life case of the Arushi murder case, the serial starts advertising her death in a similar manner. After much public criticism, the serial denied that it wanted to cash in on the Arushi murder case.
However, soon after, Tanu starts becoming even more confrontational, not caring about whom she is speaking to. She even starts learning secrets of the others in the family and threatening them with their secrets. Soon after that, she is found murdered, poisoned by a chemical. Her friend was suspected of the murder, but soon after that, her friend is also found murdered. And Om Agarwal is suspected of the murder on the basis of some evidence (the evidence seems to be incredibly light, and seemingly with no actual proof).
The complication in this is that Tanu's friend who was also found murdered, was the son of Aditya; which was a separate story. Aditya was a person from England who seemingly saved Parvati from being accused of adultery, and became very trusted. So trusted in fact, that he managed to easily deceive Om into transferring the entire business over to Aditya, leaving the Agarwals in so much penury that they could not even afford to spend the Rs. 4 lakh plus for an operation (although Rs. 4 lakh is a very high amount to spend for an operation).

Tripti is back in Kyunki Saas Bhi Kabhi Bahu Thi

After Tripti faced a court case and was shown to have become crazy, it would seem that she had exited from the serial. However, she is probably the one to have made the quickest re-entry. Hardly had the entire issue about Mandira and Juhi Thakral died down that the serial brought forward the old issue of KT, Ansh's son Eklavya and the return of Lakshya from his forced trip abroad (when KY got married to Eklavya).
Anyhow, Lakshya is back, and one was never sure about what KY wanted. She was not exactly very enthused about having Eklavya as her husband, and he is insanely jealous; but she is traditional and Eklavya is after all her husband; so she counsels Lakshya that there is no point cribbing about the past. Lakshya must move on, and he does in a very quick way.
Lakshya had gone for a wedding along with Joydeep (one no longer knows what the relationship of Joydeep with Bhumi is, they don't focus on that anymore), and there he encounters his friend getting fresh with the to-be-bride Vaidelhi and she does not appreciate even her would-be husband trying this with her before marriage. So she fights back, and Lakshya helps her. When faced with the issue about who will marry her now, Lakshya steps forward and marries her, and then returns to ShantiNiketan.
And then the twist, Tripti is actually the badi maa (respected elder parent type), and she instigates Vaidehi to file a case of attempt to burn. So, now Tulsi and Ganga are facing charges of trying to extort dowry. Nobody can believe this is happening. Lakhsya reacts most violently. Fortunately, Vaidehi realize that Tripti is trying to take revenge, and takes back her charges. So it ends well this time, but with Tripti back, one does not know for how long.

Teen Bahuraniyan - moving into the ghost zone

This typically has not been seen before. There are not that many prime time serials in the past that have brought in a ghost / spirit into a hindi serial that appears on real time, but Teen Bahuraniyan on Zee TV has done that now (maybe their TRP's were going down). Other serials in the past have used the concept of a ghost, but have later explained this as the tactic of someone to scare another person, or to get them to reveal the truth.
In Teen Bahuraniyan, the spirit is of Kaajal, and she appears to possess Bindiya (who has otherwise been shown to be a very sweet but also the least intelligent among the bahus of the house). So, Kaajal suddenly would take over Bindiya, with the objective of defeating her own sister, Payal, who has just entered the house as a new bahu. Of course, in the serial, the expectation is that everybody in the house will believe Bindiya when she makes all sort of allegations against Payal (maybe because she has been a member of the household for a long time).
The only time when you can be sure about Bindiya still surviving her independent spirit is when a mandir or some puja is involved, in which case Kaajal has to leave Bindiya, and then the Bindiya who comes back cannot understand what all is happening. And of course, other people in the house are not able to understand either.
