Season 5 marks the first full season of Castle where the show’s two main characters — Castle and Beckett — have been in a committed relationship, but will their union last all the way up until the show’s May 13 Season finale?

As usual, series creator Andrew Marlowe gave a cryptic yet thoughtful answer about Caskett’s trajectory and where the relationship will stand in the finale, telling TV Line, “You have a great map, but it’s like driving through fog a little bit — the closer you get, the clearer it gets. So about seven or eight episodes out, I knew ballpark where I wanted to land.”

In other words, Master Marlowe knows what the state of Castle and Beckett’s relationship will be in the finale, but he’s not spilling the beans. Smart man!

He did, however, give fans some other clues about the season’s last episode, noting that it will not involve Beckett’s mother’s murder because he wanted something “quieter” and “more emotional.” Instead, he reveals in this year’s finale that “something comes out of left field that both characters have to wrestle with, something that would be a challenge to any relationship.”

Ooh, color us intrigued! Could this “challenge” be something else from Beckett or Castle’s past? Tell us your thoughts and theories below!
