PS: this what I felt after seeing yesterday episode, this is just my POV..
Yesterday episode, I felt Arhaan, Salman and BB prepared script to play prank bringing the rumours on Arhaan spread by ex GF and rashmi saying i know everything then to show how pure their love is and to make them marry in the show... This is what they decided and want to get her genuine reaction.
But BB went a step ahead and bought his child and loans matter which his ex GF filed a case ( i think case was filed after Arhaan re-entered, so Arhaan too has no clue). They thought Arhaan might have told Rashmi.
When salman bought the topic rashmi shocked everyone by saying she donot know. Arhaan lied that he told her but Rashmi denied and infact panicked about loans which put BB and salman in dilamma what to do and how to correct the mistake.
Rashmi as expected handled the situation maturely.
Salman started damage control after that coolly saying you should be open and asking contestants not to talk about it.
Tomorrow he tried to talk to both of them. But just wish they wonot force rashmi to accept Arhaan because in this emotional state rashmi might say yes but i donot think once Arhaan evicts and BB ends rashmi will continue her relationship.
