Shiv is a shekhar and adoption wont pose any problems as Ira cant have any hold over Shiv and anandi from now onwards.
Sanchi will be feeling like an orphan without a real sibling. Now she should not have any problems with anandi as Shiv is not her real brother and anandi is not her real bhabhi. Cousin brother and cousin bhabhi.
Mahi will be happy to have shiv as own brother.
Ira may start feeling jealous of CM. She is no more Collector's mother.
It wont make any big difference to BH folks.
Daddu was speechless and so were sanchi and mahi.
CM wanted to hide the truth even at that moment.
It will take Ira sometime to realize that everybody pondered to her making sacrifices. And she is accusing them.
Now Ira may forbid anandi from taking any interest in sanchi.
