Oh, yes, Castle fans, it really happened.

The Season 5 premiere of this beloved ABC series kicked off with Caskett at their most adorable, making it clear this couple is in it for the long run. But not for the public run just yet.

In the official ABC teaser for next week's "Cloudy with a Chance of Murder," we learn the steps it will take for Rick and Kate to keep their relationship a secret. And we also see guest star Jodi Lyn O'Keefe straddling Castle in her underwear.

Wait... what? Watch now and then try to decide between Nathan Fillion and Stana Katic. They have BOTH advanced to our Tournament of TV Fanatic championship!
