Rick Castle and Kate Beckett have literally been a couple for less than 24 hours — remember, tonight's premiere picks up exactly where Season 4 ended — but it's never too early to start thinking about the future, right?

Although Castle star Nathan Fillion warns fans to slow down a bit — "Oh my gosh, they only just got together!" he said in a recent interview with Entertainment Weekly — he admits he could eventually see Castle and Beckett walking down the aisle together. But not for a really, really long time.

"I would say — my humble opinion, with my own eyes seeing into the future — I would say them getting married would be a really lovely series finale. Years from now," he confessed.

But in the meantime, Nathan would prefer to just let Castle and Beckett enjoy the honeymoon phase of their relationship.

"I think they’re going to have to wallow in that for a minute or two before they start thinking about the next step. They only just got in bed," he said.

If their bedroom activities are anything like co-star Stana Katic has been teasing, we're A-OK with that.
