i don't know if ganga will really marry rudra. but I hope she doesn't. because that would go against what she stands for. her self respect and dignity are her greatest strengths, she knows the truth of who is her baby's father. if she refused to marry sagar because he didn't believe the baby was his, yet he was willing to marry her believing the baby was someone elses, but on the condition that she owns up about the so called real father of the baby because she didn't want his sympathy . the how can she accept rudra marriage proposal when that too would be out of sympathy.
then what will she do when sagar realises that the baby is really his.
yes she should have agreed to the DNA test and then walked out. but now it would be better for her to have the baby on her own right in front of their noses, showing the chaturvedi family that she is tough as steel. then present them with the DNA proving that the kid is sagars, and then tell them to stick is up theirs... . live with the kid as a single mother, and let sagar wallow in the guilt of not trusting her when she needed his trust. and that his love for her is a farce. that dadi's and niru's understanding of a persons character and nature is next to zero.
