“Old habits,” Parker says.

“And really, his confusion is understandable.

Then the team’s summoned to the scene of the possible suicide of retired helicopter pilot Tommy Miller.

Good to see Dr. Grace again!

So where’s he been spending his time?

As the investigation gets underway, Torres (Wilmer Valderrama) gets called to Hawaii.

NCIS: HAWAI`I

Geez, what an unlucky assignment, right?

McGee and Knight have both heard rumors about Torres and Tennant, a.k.a.

As Rule 39 says, there’s no such thing as a coincidence.

They’ve just started seeing each other, and Kasie’s excitement is adorable.

I love this for her!

Grieving dad Jordan’s also caught on camera watching it happen.

Whaddya know, Tommy’s brother-in-law Marty drives a silver SUV.

He admits that it was a fluke that he spotted Tommy with his other family.

This doesn’t quite sit right with the team, so they call in wife number one, Olive.

The DNA was only a partial match to Marty, which means it could also come from a sibling.

She grabbed a pipe and swung it, and he stumbled over the edge of the building.

Fornell empathizes and asks Jordan to tell him about Sally.

See you in theNCIS: Hawai’ihour for the rest of the story!

But their assailants disappear as suddenly as they arrived, taking the witness’s body with them.

So much for any dreams Torres had of being a tourist in paradise.

Back at HQ, we meet the rest of the Hawaii team and get a rundown on the case.

Fortress employee Greg Winslow took the blame for the blast and was fired.

He died shortly afterward when his SUV plunged into the Potomac.

Yes, it’s as sus as it sounds.

Kyle Jennings, the only survivor of the blast, has been on the run since then.

Alas, with Jennings' body gone, they’re back to square one.

And both he and Tennant agree that it’s a matter of Rule 45: clean up your mess.

Greg says the Afghanistan explosion was intentional, but he doesn’t know why.

So now we need to figure out why Jennings' body was stolen.

Presumably Jennings is the one who set it off, ending up with the shrapnel as a result.

Off T’N’T head to the Fortress training site, which is conveniently located in Hawaii.

She’s reluctant, but Tennant stresses that NCIS wants to hire Fortress for a sensitive overseas operation.

After all, he went on the run to give them Jennings, his only lead.

Torres and Tennant talk him down, and he reluctantly agrees to try.

But when they track down Greg for more information, he’s gone.

But he did leave behind pictures of three men he recognized.

They worked securing Afghan villages and found a cache of stolen U.S. currency.

However, about $40 million of it “got lost” when Fortress delivered it to the government.

Greg’s sister, meanwhile, is fine and is waiting for him at home.

Here’s hoping he can adjust to a more normal existence after all of this.
