I think that they are probably showing the powerful Rathod family breaking at the seams to show their vulnerability. The family members are all against each other right now and even the police seem to be exercising their authority. No doubt it's because someone at the station is on Mandira's payroll. She'll do anything to get back at DSR for putting her husband in jail. She's also the one controlling Preeti.
And after Preeti's lying and scheming debacle with her fake crocodile tears telling everyone that it was Teja's plan to get her and Arjun married, DSR still supported Teja. When the family members were standing around DSR's bed, he told them that Tejaswini was their daughter in-law and told Prem to treat her well. And you saw how distraught Teja was when he collapsed and when she wasn't permitted to see him. She was very worried for him because she genuinely cares for him. I really think that as long as DSR and Teja continue to support each other, you'll eventually see the rest of the family coming back. I believe it will be Teja who will straighten out the family, especially Preeti and Mandira.
I also think that there is something up with Arjun. Today there was a moment when Anand was scolding him and he stayed quiet and didn't stand up for his new wife. There was something there that made me think that there's something more to Arjun than what we know.
And as for Prem, unfortunately, it's in his nature to fly off the handle before asking questions so I think that Teja's actions will eventually make him forgive her.
