Aakash brought up an interesting element yesterday when he was firing SP.
Here we have Aakash whose biological parents are SP and g3 who are of the higher caste but it is the environment around him (nurture) that has made him hard and uncouth...
Then we have our Yash, a product of SP and Radha who is from the lower caste. Yet he turned out so refined and classy...so it is not just the khoon and caste that determines how a person turns out but the nurturing which is not just parenting but the environment around them too!!!!!!
So, Yash had the upperhand to a certain extent while Aakash had to fight for his existence and that is the reason he is so hard!!!!!!
