i too felt ramya being shrewd and clever,if you watch her expression,you can catch her,esp her eyes...When she's near watching a fight or arguement her eyes becomes attentive and she's always smiling when shading others and in arguements😆I know some have mentioned Ramya has not done anything to show she is evil as some of the ex-contestants claim. It is probably true, but I've also noticed she is quite shrewd in the way she plays the game. In one of the unseens, she and Sam have a discussion on how they both are the only ones who don't belong to any group. We all know it isn't true, but the fact they had that conversation shows they wanted to establish it for the camera. Ramya also never speaks anything critical about Bala or his gang, except to maybe explain directly to Bala when he himself seems confused.
She's grey shaded,imo..
