Rekindled

When a second fire occurs on board a cargo ship, the team goes to investigate, and Jason saves Tony's life after accidentally setting off a booby trap.

The team recovers the stolen files, and finds out that Aquamarine was a list of Navy ships that had been installed with the faulty wiring.

Tony eventually explains why to Ziva and McGee: when he was a senior in college, his basketball team was in Baltimore for a game; while out for a walk, he saw a building on fire and rushed inside.

As Jason is leaving NCIS, Tony sets the record straight, telling him that he had to make a choice, and that rescuing him was his inspiration to become a police officer.

"[...] the fire "stuff" worked fantastically, which allowed us to tell the FULL story behind the kid Tony "almost lost in Baltimore."

"Rekindled" was a fitting title for an installment in which Tony crossed paths with a boy who changed his life forever and vice versa, and we were reintroduced to the mysterious Phantom Eight.

Rather than simply having a guest star randomly tell us something about DiNozzo, he relived the past while working with Jason King in the present".
