I know this is story anything can be shown
Diya is a doctor herself
So no hospital or doctor will agree to put her in asylum the way Rudra and Maya forced her too
Doctors have strong bonds and associations
If one doctor does anything wrong in treatment no other doctor will ever admit it ever in india atleast
Their bonding is so strong that they will cover up for each others mistakes too
But here they show a doctor being sent to mental asylum because some Rudra and maya want it
Rudra and maya are not her blood family too, hence legally they cannot send her to any hospital they have no legal rights at all to decide her fate
So although everyone says go to asylum a psychiatrist can test her and say shes normal
Anyway she herself is a doctor she will get very special treatment in any hospital etc
No one will just drag and lock her up
She does not look mentally sick shes only depressed at most may be - if diagnosis is done she will be found normal
