Foiling a revenge kidnapping, of course.
Page is also a lifelong friend of one Timothy Farragut McGee.

The boyfriend thinks the kidnappers are military because of their shorthand and their weapons.
I knew the moment you took this job Megans life would be in danger, he spits.
Then Porter heads to her house, which is swarming with agents and also is AMAZING.
How much does this job pay?
The kidnappers finally call to demand $10 million, no cops at the exchange.
Fornell says if its a ransom, it must not be political.
But Gibbs counters that if its just money, why target SECNAV?
Either way, Gibbs tells Porter that he wont let her do the drop.
I dont take orders from you, Gibbs, she says.
Then she looks at Gibbs, Fornell, and DiNozzo and asks which one of them to send.
They said no cops.
Have you looked in a mirror?
Don Johnson or Colin Farrell?
DiNozzo wants to know.
That just leaves Richard, so he paces until the kidnappers call and direct him to a parking garage.
Of course, Gibbs, McGee, and Fornell are on scene and follow him.
Page gleefully mentions that one time DiNozzo kissed a guy.
Ugh, theyre STILL making har har, gross jokes about this?
That was season 1, and its now 2016.
Tonys quite chill about it.
Lets mooooooove on, guys.
Welp, that went badly.
But Gibbs is trying to figure out why, if theyve got the money, they kept the girl.
Or the verbal key in.
He responds by asking for a pen and using it to fill out a form.
Can you do it or not?
She says she can, and were left wondering what, exactly, it is.
A background check on Richard shows that his biofuel company is close to going under.
Suddenly, Justine becomes much more interesting.
By the time they get to her house, though, shes dead from a bullet to the head.
Two years ago, Dixons unit conducted for-hire black ops missions.
So now we know that Justine was working with Dixon and was killed so she couldnt ID him.
One final call from the kidnappers has them demanding an escape plane.
The planes a decoy, and the kidnappers are smuggling themselves and Megan out of the country.
NCIS prepares to head out, hoping for backup against the angry, armed special ops team.
And sure enough, REACT is there, suiting up at Gibbs request.
At the helo pad, NCIS confronts the kidnappers.
The rest all surrender quickly.
As Gibbs arrives at Porters house the next day, Fornells leaving to visit his daughter Emily at school.
He and Gibbs fist bump.
In her spacious, highly enviable kitchen, Porter tells Gibbs, Maybe its time I reevaluate my priorities.
But is stepping down whats best for her family, or is she being ruled by fear?
Family is important, Gibbs offers.
Then Megan enters the kitchen, and Gibbs returns her ring.
I knew youd find it, she says.
Gibbs wants to know how.
My moms talked about you, she replies.
The wisdom of Gibbs transcends generations and continents and galaxies.
