In the new episode "Can't Take My Eyes Off You," Nell (Renée Felice Smith) continues to keep Callen (Chris O'Donnell) in the dark about their team's search for Katya, but he succeeds in tracking down the person who has been tailing him in a remote location that is teeming with Russians. Ultimately, he finds himself face to face with Anna (recurring guest star Bar Paly). Nicki Micheaux and Alex Portenko also guest star.
