'Castle' revolves around a celebrated mystery novelist, Rick Castle, and NYPD detective Kate Beckett. They team up to solve a case of a copycat killer, who re-creates murder scenes from Rick's novels.
Eventually, the writer and detective, played by Nathan Fillion and Stana Katic, form a working as well as personal relationship. They got married in the beginning of the 7th season.
Amann, who became the showrunner from this season with creator Andrew Marlowe handing him the primary duties of the ABC show, said he was not surprised by its popularity in India.
In the 7th season, which airs every Wednesday 10 PM on Star World Premiere HD in India, Castle and Beckett went through hell as they confronted formidable villains like Tyson and Nieman. But now that they are dead, Amann is not averse to introducing another enemy.
Another plotline that fans have started talking about is introducing a baby in the mix now that Castle and Beckett are married.
Amann says the possibility is being discussed but it is more of an "ongoing conversation".
