With Ishita talking about her phone in last episode this will hopefully tick in someones mind to look at Parmeets phone to see when the messages were send. (MAY BE LEAD TO PROVE HER INNOCENT)

Cos - Mrs Bhalla, Raman, know that Ishita has not taken her phone all day and been on charge at home.

Also

I think Raman will start his own investigations by starting with Sarika. And plus he is CEO so he will try investigate what happened in Dubai.

Also on a number of occasions Rinki has seen Parmeet hanging around Ishita

Vaishaiki, cinema day.

Also Ruhi saw Parmeet holding Ishita hands on Ashtami day.
