Assuming the promo is true and Abhimanyu does get the custody, the possible reasons for Akshnav losing it are,
1. Abhinav's finances
2. Akshara's anixiety/panic attacks
Finances can be sorted out with child maintanance but the 2nd reason might make Abhir's custody go to the biological father, atleast temporarily?
The makers have been addressing people's arguments regarding the story on way or other. Either as dialogues through Manjari, Shefali, Surekha etc or tracks like Abhinav wondering if Akshara's is being with him cuz she is indepted etc. One theory that I have seen often is Akshara is escaping from reality and her happy family is a facde she is using to run from the truth... something along these lines. I think this could be addressed with a mental health track.
Akshara loses Abhir's custody either temporarily or permanantly cuz for her anxiety/panic attacks. While we have a track with Abhir living with Abhimanyu and coming to terms with what he wants and how their relationship pans up, we get a parallel track for Akshara where she goes to a therapist where the whole escapism argument can be dealt with. With the therapy sessions, it might make her pause and wonder a lot of things and then after some incidents and a self journey we get a conclusion. Then Ak fights the case and wins Abhir's custody back.
We still didnt get a proper confession b/w Akshnav so either this track leads to Abhir coming home, Abhinav supporting AK throughout and Akshnav getting a proper confession, and a kind of realisation track for her(?) OR Akshara concludes that she really is escaping and we get Abhira(I will lose my respect for Akshara if this interpretation is correct)
P.S. One thing I really want to see if she goes to a therapist is a convo on how there are different techiniques to handle panic/anxiety. Music, humming, singing is one of them but there are other ones and we see AK practicing them too.
