Ravi's wife letter hints stuff about Carol and Ravi's relationship. Ravi reads it and is shocked and asks everyone sitting in the Blue Room - 'They show everything?' Carol, bechari, is sitting alone, smoking.
I feel Bigg Boss has blown Ravi-Carol relationship out of proportion. Ravi's wife is practically accusing him of infedilty. But to a certain extent, Ravi is to be blamed. If he had seemed not to make advances towards Carol, none of this would have happened!
