Keen fans of ABC's "Castle" are wondering if Nathan Fillion and Stana Katic's characters are bound to have a baby next season. Diehards of the show should also prepare for the potential change in the storyline following Beckett's possible entry into the Senate.

There were a lot of online speculations about "Castle" before and after the show's season 7 finale. Some reports claimed that the ABC mystery drama will conclude after seventh season while others speculated that Stana Katic, Kate Beckett in the series, will possibly leave the show.

When ABC officially renewed the show for another season and Beckett announced her return, diehards of the show became ecstatic. "Castle" season 8 intel are still scarce at the moment as Alexi Hawley, one of the series' new showrunners, revealed that they are still in the early stages of production for the eighth season. However, Hawley hints that season 8 will center on Castle-Beckett romance.

"It's very, very early days. At this point, we haven't even sat down and talked about it yet, Fundamentally, Beckett and Castle's relationship has room to have movement in it," said Hawley, who will team up with Terence Paul Winter to continue the story of ABC's hit series.

Exciting things are waiting for the fans of the show as "Castle" season 8 might reveal Kate Beckett as pregnant. According to a report, during the Poe Pen's Career Achievement Award scene in the season 7 finale, Kate did not drink during the toast, sparking pregnant speculations.

Stana Katic's character in the show could also lead next season into a different storyline a la "House of Cards." The ultimate episode last season hinted that Kate could enter the Senate and make the show more political.

There are definitely a lot of things to watch out for in "Castle" season 8 including the Castle-Beckett love affair. The show's central couple might also start a family with the possibility Kate being pregnant. Stana Katic's character will surely shine next season with a possible career change that could give the show a different vibe.
