The episode 13 of "Castle" Season 6, "Limelight," will throw-up a twisted case as well as make Beckett think about her engagement to Castle. The murdered victim this time is a young pop-star, Mandy. The media hysteria over the pop star's death will make Beckett realise that she is marrying a famous person. Like the dead pop-star, Castle also enjoys the celebrity status and lives constantly in the public eye. He is no stranger to fame, but Beckett is not part of the glitzy world.

This seeing of Castle in a new light will perhaps begin when Castle and Beckett will visit the site of murder. Media persons are already there, with their cameras and mikes. In the sneak peek, one can see a reporter asking Castle whether he is getting back with his ex-wife. One can hear him ask Castle: "Is it true that you're getting back with your ex-wife?" Castle does not answer the question, saying that it is not about him, today.

The sneak peak shows Beckett asking Castle why he did not deny. According to Castle, if he had denied that, a report would have been published that he is getting back with his ex-wife. The report, however, does get published on page six of a newspaper, as the second sneak of "Limelight" shows. The headline of the report is "Castle Caught Cuddling With Ex-Wife Publisher."

After reading the report, Beckett can be seen asking Castle if she should be worried about his commitment to their engagement. Castle cannot announce his engagement to the media, as Beckett does not want to become a public figure. It will be interesting to see what kind of adjustments and compromises both Castle and Beckett make at the end of "Limelight."

Meanwhile, the investigation into the death of the pop-star will lead to a shocking revelation. The sneak peek of the upcoming episode shows Mandy's mother claiming that the dead body is not that of her daughter.
