The upcoming episode of NCIS LA Season 5 also brings Erik Palladino back as CIA Officer Vostanik Sabatino. Could this cause a problem to the "Densi" love team?

NCIS LA Executive Producer @JPKouz tweeted December 5 that Sabatino would cause confusion and raise suspicion on his motives why he's in Afghanistan.

In NCIS LA Episode 12, Deeks will be partnering up with Nell. We already saw Nell enter the field on Episode 5. The upcoming mid-season finale could mean that Nell will be exposed to more field experience this season.

The upcoming episode also features guest star Gossip Girl alum Michelle Trachtenberg. She'll play the role of the Senator's daughter named Lily. Lily is a witty and intelligent environmentalist/private chef who has been attacked in her home.

Executive producer Shane Brennan shared his thoughts on Trachtenberg guesting, "We're very excited to have Michelle guest on the show. It's a very intense episode which pairs Michelle with Callen and Sam, in what is probably one of our biggest action shows so far this season," Brennan said.
