Do Castle and Beckett regret giving in to their feelings for each other at the end of Season 4? Not in the slightest.

In the promo for Season 5 of "Castle" (above), Castle (Nathan Fillion) and Beckett (Stana Katic) discuss the events of the "biggest night of their lives."

"So you liked it?" Beckett asks, buttoning her shirt. "Yeah," Castle replies. "Me too," Beckett says.

"Castle," which centers on the lives of best-selling mystery novelist Richard Castle and NYPD detective Kate Beckett, had quite the finale in May -- and was appropriately teased to HuffPost by series creator Andrew Marlowe.

"In the finale, the characters are ready to have this conversation. The characters are ready to talk about how they feel," Marlowe said. "So we can make that promise to the audience that all the cards are laid on the table in the finale."

Find out where things pick up when Season 5 of "Castle" premieres on Mon., Sept. 24 at 10 p.m. ET.
