Im going against the mood of the thread right now, but I was contemplating the questions Rajat Sharma asked from Rashmi and Sid.
It is my conjecture that Arti, Rashmi and Sid all three knew much before the start of Bigg Boss that they will be in it. They probably also guessed / interpreted that the makers want a triangle of sorts from them. I personally think that Rashmi and Arti wanted to give it a try but Sid shut it down before coming to Bigg Boss. The constant reference to meeting and clarification between Rashmi and Sid, Arti setting that meeting up and Arti and Sid having a fight before the start of Bigg Boss. This theory makes sense to me.
And amongst all of this Shehnaaz turns up. If that is the case such a wonderful fallout of pre-made plans.
