McGee (Sean Murray) flashes a wedding ring and it seems that he might be proposing to Delilah (Margo Harshman) while working a case on a ship. Meanwhile, one of the lead characters will be leaving the series – Dr. Ducky (David McCallum).

Spoiler TV revealed the synopsis of the upcoming fourth episode of "NCIS" season 14, titled "Love Boat."

"After the body of a navy lieutenant is discovered aboard a destroyer during a tiger cruise, when civilian guests are allowed to spend the night on the ship, Gibbs, Quinn and Palmer travel out to sea to investigate. Also, McGee contemplates the perfect proposal for Delilah Fielding."

Gibbs (Mark Harmon), Quinn (Jennifer Esposito), and Palmer (Brian Dietzen) will be working on a case in what was termed as a "murder boat" that appears to be involved in a number of things, aside from the murder. A pop star aboard the ship seems to have a connection with the ongoing investigation. Given the title "Love Boat," it is speculated that McGee will be proposing to Delilah in the "murder boat."

Although there are no other details about this anticipated proposal from McGee, he is seen sharing his ideas to Abby (Pauley Perrette) in the episode 4 promo from Spoilers Guide, and she responds enthusiastically while she gives McGee a congratulatory hug.

Meanwhile, McCallum has hinted that he will soon be leaving "NCIS." McCallum shared in one of his interviews that the main reason for his departure from the show is his health and his age, according to the Morning Ledger. He explained that working is very different for him now that he is 82 years old, as compared to when he was only 28.

Although the team of "NCIS" is already working on a storyline for Ducky's exit, he may stick around for one more season.

"NCIS" season 14 airs every Tuesday at 8 p.m. EDT on CBS.
