what happd to sheena?

i know i shud post this question in the helpdesk but i already typed it here so hope u dont mind..thx a lot

why and how did sam/sheena part their ways? and why is rv taking revenge from dia??

and what about mayank?

well, in short samrats ex gf held pool party at his farmhouse and invited everyone there. she made up a drama saying that gunjan pushed her in the pool, bt mayank proved her wrong and anyway samrat didnt believe her from the first. they broke up. then rv designed a car accident and made it look as if sam was responsible. so the police took away samrat. he's on bail now. rv said in the college that dia had slept with him. dia is broken-hearted. gunjan and nupur and uday console her. meanwhile mayank benji sam nupur gunjan uday etc are trying to find a solind proof tat will prove sam innocent and show tat rv did it all. mayur has been having cute nok jhoks and some romance.
