Castle may not be breaking network ratings records, but over the past four seasons the Nathan Fillion-lead procedural dramedy has carved out a loyal audience thanks to its endearing ‘will it happen’-relationship between Detective Kate Beckett and novelist Richard Castle.  The show illustrates a fantastic staying power that few dramas have acquired as it continually puts out 18-49 demo numbers in excess of 2.0 despite its fading lead-in that is Dancing with the Stars.  With that being said, there have been questions about the obligatory conclusion of the romantic tension between the series’ two main characters and whether or not bringing that full circle would be equivocal to ‘jumping the shark.’

This week’s news concerns just that as Castle creator Andrew W. Marlowe shared an inch of his plans for the relationship at Paleyfest.  He insisted that the threat of losing its allure will not be a deterrent from ultimately resolving the relationship.  Furthermore, the producer went on the record saying that he does indeed know when the duo will finally get together.  Marlowe stopped short of saying when that will happen (as that is part of the fun).

Going beyond that, the event also featured a nod to Adam Baldwin’s reunion with Fillion which will come by the end of season four.  Baldwin’s character will be that of detective Ethan Slaughter, and the hope many fans have already have is that it will be of the recurring variety.  The actor recently came available for a stint on Castle after the series finale of Chuck freed him up contractually.  He previously worked with Fillion on Fox’s Firefly as well as the Joss Whedon-directed feature based on the series.
