Disclaimer : Let me start by saying I don't have any special fondness for either Jasmine or Rubina I'm just curious at how things are developing between them hence initiating this discussion to know the forums views on this. This is a post meant for discussion so it's not a bashing post.
So Jasmine seems to have made a deal with both Pavitra and Abhinav at the behest of the advice of Aly. She hasn't back stabbed anyone and just made sure she secures her position.
If the precap is to be believed Rubina is shown telling Abhinav that Jasmine can't be trusted. Now my point is Jasmine has been a great friend towards Rubina and Abhinav so far and hasn't back stabbed them she is simply saving herself by neither pushing either of the people so is it right for Rubina to doubt Jasmine's loyalty?
