Malti trusts Lalit more than Aparajita despite knowing the atrocities the latter had done. She doesn't think from Aparajita's viewpoint.
Aparajita endured Lalit's tortures for the past 4 years. She's also paying the loans that Lalit took in her name. Yet Malti is obsessed with Aparajita-Lalit marriage instead of supporting her divorce.
Only Renuka in UKA can beat Malti.
