Arjun's lawyer Karthik without going through it properly presents it to Arjun which he signs. Vandana now demands Pooja quoting the statement in it. Priya gets devastated and pleads Vandana not to demand Pooja, since Pooja cannot imagine living without her and vice versa. Priya goes to the extent of begging Vandana and falling at her but Vandana nevertheless stays stubborn over her decision. Vandana hires a successful lawyer for this case. After unimaginable depressions and worst nightmares of losing Pooja, Priya decides to evade with Pooja, while the latter is completely innocent of what is going on. Knowing that Priya has absconded with Pooja, Vandana adds a feather to her cap making her side stronger and filing a criminal charge against the Priya for her act.

He then promises to support Priya to get back her child and Priya becomes highly delightful. Meanwhile, Adhi develops a complex and is heartbroken thinking that he is unwanted by Vandana as well as Arjun's family and bursts out to Arjun about it. Moreover, the psychiatrist advises Adhi to be in Priya's custody for his better future and for his better mental health. Arjun then decides to retain Adhi first and then to fight for Pooja's custody later.
