My tracking starts from the point they were destined to get married. Yes, I would like to say destiny like RK says kismat. Because otherwise there was no reason for MB to pursue a superstar for bringing him to justice when the VICTIM's family itself was ready to drop the charges.
Round 1 - RK makes MB his wife and MB taking vows that she she will never break down to RK directed humiliations. Personal humiliations begin and end as MB wins the round 1 as she gets pretty settled being the 9 naukrani and spot girl to RK as long as her father is getting treated and is on the road to recovery.
Round 2 - Instigating Each Other to bring out the worst
Tick Tock Game - Not sure at this point if it is going to be Triathlon or a Pentathlon or a Heptahlon or a Decathlon !
Event 1) RK Instigating MB out of her compliant attitude - RK Wins
Attack: Insulting your mother. Result - I see the spark back in your eyes.
Kuch der pehle ajnabi si lag rahi thi, Ab apni si lag rahi ho.
Event 2) MB - I will fight for my mother's honour in 24 hrs.
How ? I don't know... You are too mighty for me an ordinary girl. But with grace of Bappa, I will have soon some help getting my way. Bappa has blessed me with an anonymous letter and some pics. Now I can leverage this opportune finding to have the superstar RK apologize to my Mommy.
Result - I win. I see the hurt pride in your eyes.
Ek Mamuli si ladki ne ek superstar ki yeh dasha kar di.
Event 3) RK - I will avenge myself and show you what it means to cheat me.
You targeted my memories with my father. You desecrated those memories by flashing it for public display and talk. Now I will target your existential bonding with your father for whom you willingly sold yourself off to me. Let me twist the story and present it to your father. Tit for Tat. Cheat for Cheat.
Result - to be known tomorrow. Per spoiler updates, MB is hurt to the extent that her commitment to keep the deal with RK working is crumbling.
