Interesting observation,I personally feel, BB gives the wild cards a recipe of what is expected of them when they enter the house obviously to make it more interesting but that comes with a expiry say a period of say 2-3 weeks by which time the inmates form a twisted opinion about these wild cards and thus wild cards are kind of left vulnerable finding their own identity - we know for instance that's its not that easy to changes first impressions and probably Priya is going through this phase, before she actually pitches her originality in the true sense.
