We open with Leon Vance (Rocky Carroll) visiting his late wifes grave on her birthday.

His emotional visit is interrupted by the unexpected arrival of his son, Jared (Spence Moore II).

And theres a reason for that: father and son are estranged.

What makes NCIS so damn special?

But a softwhumpends the argument when Vance is shot in the back and collapses into Jareds arms.

He begs the team to catch the guy who shot his dad.

Three explosions immediately rock the cityscape in front of them.

Despite whats reported on the news, those three locations arent random.

That would be retired FBI agent Tobias Fornells (Joe Spano) garage.

Ive been saving the asses of NCIS for 20 years, he explains.

Its clearly time for Team NCIS to assemble.

(Jared takes this as his cue to disappear.)

But of course, the news of the explosions has Vance’s heart monitor beeping wildly.

Still, he appoints McGee acting NCIS director (love this for McGee!)

and shares essentially the same diagram Jared drew.

Then he asks to speak with his son.

But Jareds busy chasing down McGee to apologize that his dad pressured McGee into putting his family at risk.

Its a panicky moment that turns out to be all false alarms courtesy of a Bandium hack.

It convinces him to stick around, even spending the night in Kasies (Diona Reasonover) lab.

Good thing he did.

Thats when she signed up for shooting lessons and found Jared on Bandimatch.

Its actually a ruse to interrogate him, with Curtis taking point.

So were back to Lindsey, who cops to planting the virus on Voss phone.

And thats when Fornell puts it together.

He heard that quote more than 20 years ago on his first case with Gibbs (Mark Harmon).

As Jareds childhood memory unfolds, were treated to scenes from theNCIS-verses past.

A plague-stricken DiNozzo (Michael Weatherly) in season 2s SWAK.
