Om & Rudra were also part of her mission exposing Tia once but it back fired.
Anika is again going to prove Tia is married but Tia will smartly ruin the proof.
Om was standing there when Anika told Shivaay about it.
Now Om might tell Dadi about it as Om & Dadi know Anika never has been so irresponsible. Om will tell all the details to Dadi andand Dadi might bethe one pressurising Anika to save Billu. Since Anika always resists going the wrong way. She will not go with Dadi's plan but somehow she'll do it with Dadi, Om, Jhanvi aswell maybe support.
As we remember anika is yet to pay a big amount of money to Dadi so she might blackmail her using that š
It's better to wait for the actual sequence.
