Nice question.I don't know where the cvs are going with the present story-line of 'HD',but I'm sure about one thing that,they don't do their homework before writing a particular scene.The way they've written today's episode,it does give us a view that Indira is indeed having a certain change in her mental state.But I don't think she is having delirium,because the most common causes for this clinical state are:brain tumor,kidney failure,stroke,and low,or high blood sugar levels.And Indira surely is not suffering from any of these problems.If anybody is having delirium its the cvs,and the writer of 'HD'.They need help!
