What is Avni's plan

I am unable to understand Avni's plan. She is becoming desperate and leaving her mobile in Mehta's house when she learned that Aman is coming. What exactly Avni and Neela want? They are behaving as if Aman is a little baby, they can carry him in their hands and run away. 😕 Why did Neela went to airport? It will take time for them to win Aman's heart. Avni's expressions will definitely be suspect able for DaYA and cunning detective Diksha. Why is she not understanding

I'm also very much confused.

Yes! Her emotional turmoil is also barricading her from her revenge plan, because after the engagement fiasco, she hasn't really done anything to break off neil-riya's engagement, which she needs to do if she wants to stop daya from getting back her wealth and status again, because the girl is just busy in playing a convincing friend to riya, daya's pet and a mere jasoos who is running away from neil's eyes; when is she going to do something to break the alliance of neil-riya in all this? I want to see more avneil romance, which we are thankfully, albeit slowly, getting since a few days, and the new on-location shows some sweet eye-lock exchange between them after neil's accident, with avni administering first aid to him.
