With the holidays upon us, big things are bound to happen on all your favorite TV shows. A new teaser for NCIS: Los Angeles‘ Christmas episode, which will air Dec. 15, reveals that it is no exception.

The teaser, though brief, shows Callen in love, guys dressed as Santa Claus, and something very promising for “Densi” fans. (Was that a kiss that almost just happened? Looks like it!)

The show’s creator and executive producer, Shane Brennan, elaborated in an email on what’s to come next week: “There’s something under the Christmas tree for everyone in next week’s episode. A truly heart touching surprise for Sam that centers on his family, a moment of truth for Callen and, for the Densi fans, the mistletoe moment that you’ve been waiting for all season… Definitely our biggest and jolliest Christmas episode of the series!”

The teaser will air tonight, but you can get a first look here.

Catch a new episode of NCIS: Los Angeles tonight on CBS at 10/9 c, and the Christmas episode next Monday, Dec. 15, same time, same place.
