A question...

i did feel that Sahukat (Sanjay Dutt) suffered from Schizophrenia from the very beggining and he starts to imagine the life around him change according to whatever he is writing..the lines gets blurred between fact and fiction..Antra(Aishwarya Rai) realizes this and understands the despair that Sahukat has descended into and tells him that Yash has Committed suside(more like a mercy killing) ..although yash was never there..all the film until the end was only shaukats imagination..while he was writing the book, since he was trying to base his book on the people he knew and loved..somwhere in the middle he starts to imagine things actually happening to him..all that he was writing..thats my thought..
