.@ rituparna,
1. prashant character has to be played by someone , who is taller than yash 😆 .there is a possibility of his entry after arya settles down with their misunderstanding .2.prashant is a selfish guy . he would do any thing which will benefits him.if he feels that coming back to ararti is beneficial to his claim to his parent's property then he will try to do so .mr. dudey is a spineless man who is blind in love with his son in spite of his wrong doing.3. no triangle cos arati is deeply in love with yash and hates prashant for his wrongdoing.pregnancy track will bring arya in one roof once again
