So far, fans of "NCIS" have been witness to a different Gibbs, one that looks at life through the prism of death. However, in the latest episode, Gibbs takes a step back and lends the spotlight to his agents, McGee and Bishop.

Season 13, episode 3 is aptly titled "Incognito". McGee (Sean Murray) and Bishop (Emily Wickersham) are ordered to go on an undercover assignment and they will play the part of a married couple.

The promo for episode 3 reveals a friendly banter between the two as they embody their new roles. We must say that the two share a wonderful chemistry and even kiss while acting their part. However, their main role is to spy on a marine lieutenant and his wife. Whilst carrying out their espionage, Bishop will venture out on her own and that threatens their assignment, not to mention, the anguish it causes her partner, Tim McGee.

You can read the official synopsis for episode 3 below:

"After a Marine is found murdered in Quantico hours after calling Gibbs to discuss a possible case, Bishop and McGee go undercover as a married couple to run surveillance on a Marine Lieutenant and his wife."

Showrunner Gary Glasberg told The Hollywood Reporter that season 13 will involve a major romantic twist to Emily Wickersham's character, Ellie Bishop. The new NCIS agent's marriage will be tested in this season as she and her husband constantly fight and are driven apart.

"NCIS" season 13, episode 3 titled "Incognito" airs on Tuesday, 6 October at 8pm on CBS.
