Now Indu will be knowing that Indira is her mother and zara is not indira due to mismatch of fingerprint.
Indu may bring that pakistanwali along with her and tell rishi that she is her real mother.
Rishi will be stubborn on seeing her. But still, he may not accept her as his wife as he still believes that the current zara is Indira.
This may make indu furious and hate her father and even zara may not accept rishi's feelings.
Totally no one will be happy either rishi, zara, paksitanwali, Indu SN Family and even shweta.
Time shd say the truth.
