Apparently...

Apparently the Pethewalas have never heard the phrase "fool me once shame on you, fool me twice shame on me," because they are all too willing to put all of their faith in Shreya and her rather miraculous recovery, both mentally and physically. Like by what medicinal power did she already get her eyesight back? And, honestly, if she did all that stuff before, and they already have a reason to suspect her, what would make them think Sanjana is lying (even though it's been proven that she tells the truth) and Shreya is all of a sudden some brilliantly virtuous bahu? And, on top of that, they're all such huge hypocrites considering they bent over backwards in their attempts to punish Sanjana and Ajay, but have shown absolutely no animosity towards all the evil that Shreya did. And, forget Sanjana... they literally doubted their own son... even after everything that Ajay has already been through to gain their trust again. Also... Bhushan is the biggest idiot if he decides to believe Shreya even though he has doubts on her character (as demonstrated by his dialogue earlier this week).
