Rakhi wanted to cover up her morning kaands of cursing people, that's why she gave that OTT reaction that meri naak toot gayi and all and diverted the topic. She herself said on the bed that woh subah wali baat ke liye maafi maang legi.
She also did the same thing during that weekend ka vaar when she abused Nikki and then completely diverted the topic by saying meri mundi Todhi isne.
And I'm sure she is gonna repeat all these things again and again.
PS- Aaj woh Rahul Mahajan ke kapde phaadne wali hai by again covering up through her character Julie.
