Poco - you really help my neurons develop further. Your analysis actually gives a deep insight into the person's mind which you can't see visually. I don't know how many stars can I give you (anything will be less).
Yes, Abhiya were sad, restless and in deep love. I don't have a heart to discuss them further as it has it's impact on my whole day. I will leave it to your analysis.
But I do want to talk about Madhu and Arnav. I feel bad for Madhu, really bad. She is just being a mom and that's what mom's are like. I just think of it this way - any mom would have done the same in same Indian social circumstances. Infact, Madhu is nicer - she is not mean to Pia as a person. She is just trying to protect her daughters' future. She accepted Arnav back in her life with his mistake as far as that mistake didn't affect her family. As you said, she is just a victim of circumstances till now.
On the other hand, Arnav seems to be a person with broader mindset; he is emotional, he is a good dad, he is family-oriented. I really wonder what would he have done if the circumstances were just reversed. I mean, Madhu had a kid from her past. May be he would still be so acceptable and supporting.
