@Sudha, the first line of your post itself is perfect description for this character Indu. She is never satisfied with the way things happen, and she always finds a reason to crib for something or the other and tortures people around her.
I can understand that Bhanushalis are grateful to Teni and want her to be happy, fair enough. But then they never felt like that about their own daughter in law who always selflessly cared for their happiness. They never wanted their son to be happy with his wife so wholeheartedly like they feel for Teni. And seriously, that's what makes them look like a bunch of hypocrites!!
Indu and Teni's bond comes across as materialistic and situational than something genuine and deep rooted. Indu never really accepted Shorvori fully, she was never fair to her though she always kept blowing her trumpets that she treated Shorvori like a daughter. And now she has got a readymade option in form of Teni to replace Shorvori. In case of Teni, she has someone who supports and even fuels her inner desires of having Parth and being treated like bahu of the house, so she bonds with Indu more than anyone else in the family.
I am waiting to see how far this lovey dovey relationship between Teni and company goes. Situations are going to change in coming days for sure, and it will be interesting to see to what extent this wretched family supports Teni. I may sound rude, but I want to see Indu and Teni bond breaking brutally like it did in case of Parth and Teni. Because that will make this foolish girl Teni realize how shallow and selfish Indu's concerns for her, and will make Indu realize Shorvori's worth. I doubt Indu will ever realize her mistakes though, some characters are just beyond redemption.
