A croissant run lands Jess in the middle of a cartel investigation with an 11-year-old in tow.

She also says the man who died in the car was her brother Daniel.

Before Knight can get more answers, a nurse wheels Reyna away for an MRI.

Reyna makes Knight promise to look out for Adam while she’s gone.

Oh, and the man who died isn’t her brother.

He’s a DEA agent named Daniel Tanner.

Adam reluctantly agrees to stay with Knight while his mother is missing.

That’s when Adam shouts that his mom didn’t do it because Daniel was his mom’s friend.

Mateo Serrano’s the slick entrepreneur, while his brother Isaac is the enforcer.

However, Knight’s return puts a frown right back on Adam’s face.

And he has reason to frown.

The nurse identifies Isaac Serrano as the man who threatened her family and forced her to hand over Reyna.

Frank wants tomove, but the NCIS agents urge a slower response.

In fact, he also says Uncle Daniel used to bring him sounds to mix.

That seems like my kind of undercover work until he gets confirmation that Mateo’s currently in the restaurant.

(Who is this woman?

Is she Mama Serrano?

A random cartel member?

A customer angry that her order’s been delayed?

The episode never solves this mystery.)

The original files show that Mateo was meeting someone in Lincoln Park three days ago with a bribe.

He cuts a deal and flips on the rest of the Serranos.
