Mrunal is really good actor but I guess sakshi ka character thoda alag hona chahiye..
Perhaps more mature..
But ofcourse they have introduced her as lead for Arjun .but as Gorky cleared in interview Arjun started trusting her but she come out as mole of sikandar.
But ofcourse story couldn't shape up like that as they kill whole ETF team in one go n introce new characters.
