The weapon of voting given to contestants is being used very shrewdly - as was evident in the Kirti and Shamit cases.
In the present situation, Rupu and Arpita are the only two female contestants remaining. Hence FG mangaement will ensure that Rupu is saved. Somehow!
As regards the two male danger zone inhabitants, Arijit is definitely the stronger of the two. For people like Rex and Qazi, getting Arijit out at this stage is the best possible thing to happen - since their chances become brighter in the future. Sandeep is not so popular among the janta - having joined in very late.
So it is possible that the male contenders will not let go of this golden opportunity to get rid of a strong competitor like Arijit!
