Every hero needs a teacher. It's one of storytelling's oldest shapes — the green protagonist and the seasoned guide who shows them how the world really works. But television, with its hundreds of hours and its love of moral complication, has done something fascinating with the mentor: it has made the relationship as likely to corrupt as to ennoble. The TV mentor can make the hero. Just as often, the TV mentor breaks them, and the show is about which one it turns out to be.
The classic guide
At its purest, the mentor relationship is a love story between generations. The wise elder sees something in the untested youngster, takes them under a wing, and passes down hard-won knowledge — and in doing so, often finds their own redemption. The mentor gets a legacy; the protégé gets a future; the audience gets the deep satisfaction of watching wisdom transmitted from one person to another.
The Mandalorian made this its whole engine, pairing a taciturn bounty hunter with a small green foundling and letting the gruff warrior become a father by teaching, protecting, and ultimately being changed by the thing he was supposed to deliver. The best mentor stories run in both directions: the teacher learns as much as the student, and the relationship remakes them both.

The corrupting influence
But television's antihero golden age gave us a darker model: the mentor as seducer, the guide who teaches not virtue but vice. Here the older, more experienced figure draws the protégé deeper into a world they should have run from, and the "education" is really a corruption. The relationship has all the intimacy and trust of the classic version — which is exactly what makes it tragic.
Better Call Saul is full of these poisoned tutelages, mentors who school their protégés in cutting corners, breaking rules, and silencing conscience, all while genuinely caring for them. The crime sagas thrive on the older operator who takes a younger one under wing and slowly, lovingly, ruins their soul. The mentorship is real. So is the damage. The show's heartbreak is that the kid couldn't tell the difference until it was too late.
The mentor as the show's conscience
There's a third kind, too: the mentor who exists to model a way of being in a world that's lost it. The figure who teaches dignity, craft, or loyalty almost by example — like Pose's Pray Tell schooling his ballroom children not just in performance but in how to survive and love. These mentors are the keepers of values the show holds dear, and their lessons are less about skills than about how to be a person.
What unites all three is that the mentor is really a mirror for the show's deepest question: what does this world do to the people in it? A series that believes in goodness gives its hero a guide who builds them up. A series about corruption gives them one who tears them down. Either way, when we want to understand a television protagonist, the fastest route is to look at who taught them — and to ask whether that teacher was saving them or selling them something. The answer is usually the whole show.
