Jas is a sore loser...she could never fathom the fact that in spite of being one of Colors' faces, she wasn't as popular as Rubina....even though she gained unnecessary attention from Salman on WKv, she was never appreciated as a contestant on the show....
Post her exit, she thought the audience might fight for her re entry but sadly there were only a handful of people....the more she read any Rubinav gaining popularity, the more she gt venomous....
It all makes sense now how Aly actually was putting up a sympathetic act during Jas's eviction...he had shown his true face when he said tht he wanted to break the moment between Rubinav during Abhinav's eviction so tht Rubina doesn't gain sympathy
