What Reacher Season 3 Reveals Jack Reacher Learned From Garber

Jack Reacher Implements Many Lessons He Learned From Garber

When Reacher realizes that Quinn might have abducted Kohl and tells about it to Garber, Garber reminds him of a lesson he has always taught him:“Never get distracted from the job at hand.“This serves as a stark reminder for the character to focus on Kohl’s case and ensure nothing happens to her before it is too late. Even when Reacher implies that he is going to kill Quinn, Garber asks him to"do it once, do it right.“By saying this, he erases all second thoughts in Reacher’s head, prompting him to kill Quinn in one shot without giving him the opportunity to fight back.

“Assumptions kill” has become somewhat of a credo for Jack Reacher in the Prime Video show, where he keeps reminding himself and others that jumping to conclusions without gathering all the facts and evidence can do more harm than good.

Since assumptions can kill, Reacher gives Quinn the benefit of the doubt despite knowing that Kohl would never be disloyal. He tests Quinn’s claims by asking him what Kohl’s first name is. When Quinn fails to answer, Reacher immediately realizes that Quinn is lying. This reinforces that even during situations where he is at the end of his wits, Reacher does not let his temper get the best of him. Instead, he implements Garber’s lesson of not leaving any room for assumptions before taking concrete action.

Leon Garber’s Daughter Is Another Recurring Character In The Original Books

Leon Garber’s daughter, Jodie Garber-Jacob, is also a part of the originalJack Reacheruniverse. Given how the show has already introduced Leon, it is only a matter of time before it will add Jodie to its roster. Owing to Leon Garber’s multiple appearances in the original novels, he will likely appear again in the Prime Video series' future installments. Jodie plays a prominent role in twoJack Reachernovels but is mentioned or referred to in several others.

Here are all the books that feature Jodie Garber in some capacity:

She plays fairly significant roles inTripwireandRunning Blind.
