I honestly don't want JaAn union.
Anandi has done lot for Jagya, so may be its time Jagya does something for her by saving her life and let all this remain at Friendship level.
Infact I would prefer A to give divorce to J and let GAGA setttle in the family . A should move out. B&S can always support A and hope A makes good career and life for herself.
The moral woild be that Child marriage is evil and can lead to separation of lives, but if you have fighting power like A, one can atleast find a way out of it.
J can suffer with pyscho G and that would be his punishment, while G can stay in the family and do family seva. That would be her punishment.
