ria after showing her face to RK she turned her face to other side and smirked.it shows that their is something fishy. I feel if their are no one behind ria's entry then this is a trap of ria for RK.she is sure studying about RK and his personal life.everyone knows RK is egoistic ,on premere day also one can see jealous RK and his inner turmoil.then she came across RK car on that night accident happened.she definitely came to know about Madhu's miscarriage.he coming everyday to hospital to meet her is a hint to her that when Rishbala lost their child then they both should share pain instead SUPERSTAR RK coming and meeting the stranger everyday.she may thought to bring use of this situation and create more misunderstandings between RISHBALA then she disappeared from hospital without informing anyone .then met RK doing antics maybe she know he is going or coming from ad shoot on the way so she did ,she met him,RK had lot of drinks .next day she again meets RK as working.but how could be so many coincidences that too immediately.she may wanted to become heroine so using RK as stair then show her true colors or if failed in heroine thing then she may want RK and try to get him and like sultan she again rant laga ke rakhegi that she stood by him when RK wanted someone to share his pain and Madhu don't deserve his love.RK and Madhu's love changed through so many faces but she always stood by him because she loves him a lot.ria definitely ia going to bhai part 2 only to be get out[dead] at the end of the track .
