I didnât see anyone trying to pick up rivalry with Rubina, all I see is Rubina trying to pick up rivalry with other strong contestants even without her own mudda. đ
Thereby she is trying to come to limelight. But she was called out yesterday for so many wrong things & if she keeps picking up wrong muddas repeatedly, as sheâs doing since first week, she might become irrelevant in this show. đ
This week was thanda compared to previous two for Rubina's game yet wkv was all about her so She's anything but irrelevant 
Rahul is definitely trying to form a rivalry angle with her .
He tried to form love/ hate whatever it was with Pavitra in first week -
Then he did try to provoke Ejaz with all that age shaming crap
And this week he brought nepo card against Jaan .
But nothing exactly worked out for him except Rubina. So yeah ! He's trying to milk that out to max by continuously mocking her over smallest of things conveniently ignoring pretty much everyone else in the house
