Although he wakes up alone in one scene, the titular novelist says in another shot that 'it wasn't a dream', and he and Beckett liked it.
What happens to Castle and Beckett the morning after they slept together has been teased in a new promo for "Castle" season 5. In one scene, the titular character is seen waking up on his bed with no one next to him.
However, the novelist says in another scene, "So it wasn't a dream." Beckett, who appears to be wearing a bath robe, asks Castle if he liked it. He says, "Yeah," and she says she liked it too. One of their new cases is also previewed and it involves putting together pieces of paper.
"Castle" will return with all-new episodes starting Monday, September 24 at 10 P.M. on ABC. In addition to playing out with Castle and Beckett's romance, the season will finally answer the question about who killed Beckett's mother.
