If Sharma family goes back to Kausali, then the story ends because this is Akshara’s journey and if she gets her happily ever after then the story is done- don’t they need drama to continue the show? Also, if they were to go back to Kasauli- what was the need to have Abhir get enrolled to a new school in Udaipur. They also brought in Shivu, Abhir and Ruhis bond is getting better.
I feel this is what will happen:
Shefali and Parth’s divorce and custody battle will happen first - it will be Akshara’s first case. It was mentioned that it can take up to a year to get a hearing date in higher court for Abhir’s custody- unless makers forget this and decide to rush again.
Abhir’s custody solution will be a joint custody, then they will show healthy coparenting.
Then makers will move forward with Abhi and Arohi’s wedding. I don’t think there is any Abhira reunion- Akshara loves Abhinav and is happy in their marriage, they are also currently supporting each other without Abhir. As I said this is Akshara’s journey and she has a made her choice and it’s Abhinav so no point in makers trying to bring Abhira again, especially when they have progressed Akshnav relationship so much. Also, there is no point Abhinav exit/death- no point of Abhira reunion that way either. Makers for 8 months have stuck with creating Akshnav and they did, so stick with this new concept.
Akshara and Abhinav may have a daughter.
Then either YRKKH legacy ends forever or all leads die and Gen 4 leap.
