"Chernoff, K" will introduce Anastasia Kolcheck (Bar Paly), a perfect candidate for G's (Chris O'Donnell) mysterious new girlfriend.

The NCIS agent has been in a relationship with Joelle since last year, but statements from O'Donnell and series creator Shane Brennan indicate that G and the kindergarten teacher will soon be a thing of the past. Instead, Callen is poised to couple with someone connected to the NCIS: LA family, someone who may be related to a certain Arkady Kolcheck.

"I believe there is a new love interest for Callen coming up," O'Donnell teased while speaking with HuffPost Live, last month.

"[It] ends up being connected to someone that we've seen in several past episodes," O'Donnell told TV Guide. "There's more to the story."

Anastasia (Anna) will fold into the story as Hetty's (Linda Hunt) team heads to Russia to close the books of Arkady's missing oil tanker and the flaunting of economic sanctions.
