The Gibbs' Wives Club continues to (almost) grow on NCIS.

Leroy Jethro Gibbs (Mark Harmon) isn't one to share information about his personal life, but when it becomes relevant to an investigation, the members of the team learn more about their boss. Such is the case in the April 16 episode.

Should fans expect to see a fan-favorite return in Season 16?

In "Hail and Farewell," the team looks into the death of Major Ellen Wallace (Erin Cummings), whose remains are found at a construction site, though she was believed to have been killed in the 9/11 attack on the Pentagon. Bishop (Emily Wickersham) and Kasie (Diona Reasonover) discover Gibbs and Ellen were engaged.

"Gibbs never talks about his personal life," McGee (Sean Murray) reminds the others. "We only find out about it when it's part of a case." That's when he breaks out the Gibbs' Wives Club infographic (above).

Harmon (and his character Gibbs) will continue to lead the team in the 2019-2020 season.

When Gibbs' blood is found on Ellen's clothing, Gibbs finds himself on the other side of the interrogation room table. Jack (Maria Bello) steps up to question him (since no one else wants to) and notes something very important during their conversation.

Gibbs says the reason why he ended their relationship was "complicated." However, that's different from his previous failed relationships. Usually, his exes were the ones who ended the relationships. Ellen was different. Why?

Gibbs admits to Ellen's father (Garrett M. Brown) that he left her because he loved her. "And that never ends well," Gibbs says.

"I was trying to do the right thing for her, but she still ended up here," he tells McGee at Ellen's funeral.
