Things will not go so swimmingly for our on-the-job lovers Esposito and Lanie as season 4 of Castle unfolds. Jon Huertas spoiled to TV Guide that the two lovebirds may not be on the same page when it comes to marriage.
"Esposito and Lanie's relationship is not going to be a smooth relationship," Jon Huertas says. "Esposito or Lanie might think that they want to [settle down], but the other one might not be ready to go there. That's going to create a little bit of a storm in their relationship."
