Harm meets two more NCIS special agents, Sam and Callen.

He previously met Gibbs (Mark Harmon) and his team in the two JAG episodes that served as backdoor pilot for NCIS.

Harm doesn’t think Sam and Callen will necessarily find anything. “We haven’t had any real problems since we deployed, and we run a tight ship,” he tells them.

“The safety and security of this vessel and her crew are my number one responsibility,” he continues. If there is a threat, they must identify and eliminate it immediately.

After Eric identifies one of the operatives, Vincent, on the USS Allegiance, Sam and Callen chase him through the mess hall and ship. It’s Harm who stops the suspect with an arm across his chest. “Where you running to, sailor?” Harm asks. “You’re on a ship.”

“They always run,” Sam informs the XO, who wants to know why. “Mystery of the universe,” Callen says.

When Vincent asks for a lawyer, Harm offers him some advice as one: “If you’re attacking my men and my ship, a lawyer is not going to be able to help you.”

To help with Anton Yashnikov, who has diplomatic immunity, Hetty (Linda Hunt) says she’s going to turn to a friend who’s the Marine liaison to the Secretary of State. Harm immediately knows it’s Mac (Catherine Bell). “Yes, Captain,” Hetty tells him. “And she’s right here in Los Angeles.”

Mac joins Hetty at a restaurant, to the familiar notes of the JAG theme.

Mac won the coin toss — but it was the beginning of their end. Harm joined her in San Diego and passed on the position in London. “We were engaged, but living completely separate lives,” she says.

Hetty offers hope for Harm and Mac’s future. “The final chapter isn’t written yet,” she says to Mac.

“That sounds like the lies you tell your wife: they sound good, but they don’t really hold up,” Mac says of Anton’s plan using Chechen spies for a Russian operation for plausible deniability.

Mac convinces Anton to help them by blackmailing him. All it takes is her threatening to send photos of him with his mistress to his wife.

Oh, those familiar notes.

In addition to bringing back David James Elliott as Harmon “Harm” Rabb in the penultimate episode of Season 10 and Catherine Bell as Sarah “Mac” Mackenzie in the finale, NCIS: Los Angeles brings back the familiar sounds of the JAG theme when each first appeared on-screen.

First, Sam (LL Cool J) and Callen (Chris O’Donnell) travel to the USS Allegiance to investigate a threat and meet with the ship’s XO, Harm. Then in the finale, Hetty (Linda Hunt) recruits her old friend, Mac, to liaise with a Russian diplomat.

Though there isn’t much time to spend on their personal relationship, viewers do receive an update on Harm and Mac’s romantic status — and it isn’t a positive one.
