Speculation

No one says that they are leaving 'cos they are getting better offers even if it's true, so that the current team are not offended. And Shilpa said it, which makes me wonder about the real reason.

She seems to be really close to Karan - wonder whether this upset her boyfriend?

If she does another serial or movie, in any language, her role being better than that of Ridz in DMG, then we can believe this, but somehow I don't think so....

No offence meant re: the above statement - they are just my thoughts.
