Kadambari as some Btown magazine/news editor, knows film celebrity Ritesh and obviously who his family members are.😛 She is still shown sending reporters for interviews or news coverage to Ritesh's house just like others. (Even five years back when she met Indu that night, Ritesh was a film star and his family was rich, all living in Mumbai.)
So feel there's unpredictable but touching twist with Zoon.😃
Mahesh is from Indore but we as viewers don't know much about his siblings or other family members. Indu and his father after confrontation and hospital drama with Mahesh, met Kadamabari that night while returning in a bus from Indore to Mumbai. So Kadambari's husband and in-laws are from Indore and she has returned to her home town and parents in Mumbai after dumping just born kid in a bus mercilessly, to start new life five years back with no baggage.
