NCIS will air a Thanksgiving-themed episode called "Blood Brothers," that will involve Eleanor "Ellie" Bishop (Emily Wickersham) heading home to Oklahoma this coming Tuesday, Nov. 24.

Is Emily Wickersham Getting Booted From 'NCIS'?

Bishop won't be the only NCIS Special Agent heading to Oklahoma, though. Gibbs (Mark Harmon) will follow her to make sure she's okay given the circumstances she left Washington, D.C. under in regard to her husband admitting to his affair.

The NCIS YouTube channel uploaded a preview of the episode, below, in which Bishop appears surprised that Gibbs would travel all that way for her.

"You're really in Oklahoma," she states to him somewhat questioningly, which prompts him to say, "Howdy!"

In another clip, Bishop will let out her anger as she smashes her cell phone while Jake (Jamie Bamber) is calling her. She really doesn't want to speak to her husband at the moment.

Her mother, Barbara (Lindsay Wagner) will be right by her side as the phone gets crushed.

Then, during dinner, things will get heated between Bishop, her family, including George Bishop (Ryan Doom) and Gibbs.

"This is my life! My marriage! So back off!" she'll shout before storming off.

Bishop will then have a chat with Gibbs out on the porch.

"You've done enough running, Bishop," he'll tell her, which will easily surprise her just as much as him being in Oklahoma with her.

"You are telling me to talk about my feelings," she states somewhat questioningly, which leads to him mentioning one of his iconic rules.

"Rule 28: Need help, ask," he'll share.

Bishop heading home isn't the only focus of the episode, though. According to the press release, the NCIS team will be brought into a case to hopefully spare a family from suffering from further tragedy.

A sailor battling leukemia needs a bone marrow transplant, which the team will try to locate a donor for since his two Marine siblings were killed in the line of duty.

NCIS airs on Tuesdays on CBS at 8 p.m. ET.
