The Professor is an essential character from Money Heist. Always thinking everything through, he has given viewers some remarkable quotes.

Sergio Marquina, better known as The Professor on Netflix's hit show, Money Heist, is one of the most essential characters in the five-part series. Being the mastermind responsible for the heists and guiding his crew through them, fans are able to gauge his logical and tactical personality.

Throughout the shows' five parts or seasons, The Professor has a slew of lines that make him unforgettable and dynamic, showing several sides to him aside from the straightforward and standoffish exterior. These quotes speak volumes about his character, determination and impact on the storyline.

His Opening Line To Tokyo

"Excuse Me, Do You Have A Minute?"

Simple and straightforward, The Professor's subtle opening line sparks one of the best recruitments and relationships seen on the series: Tokyo and The Professor. The Professor was like The Godfather to Tokyo, her "Guardian Angel," as she often put it.

Their relationship was one of opposites, but that's why it worked. Tokyo challenged The Professors' logic and reasoning and The Professor was the only one who knew how to reel Tokyo in. Throughout the series, The Professor acts as a guide to the entire crew, essentially leading them toward a better life, and all it took was a little intrusion.

His Motivation

“I’m Offering You Resurrection, A Second Life.”

A quote that perfectly encapsulates The Professors' personality and motivations as an individual, this line lives in the heads of Money Heist fans, rent-free. Aside from The Professors' personal motives and family history with the heists, it always meant more to him: it was about changing the lives of the crew.

Although The Professor physically needed everyone to carry out his 20-year plan, he had a way of convincing them that the heists and the money would change their lives and bring them happiness again. He made it about them more than it was about him.

When He Explains Why They're Doing The Heist

"In This World, Everything Is Governed By A Simple Balance. There's What You Can Win And What You Can Lose."

In the third episode of Part 3, the crew has entered the bank and begun to enact the second phase of the plan. In what presents itself as "flashback moments" containing scenes from the gang's time and lessons in Toledo, comes one of The Professor's best monologues.

As everyone gathers around for dinner, The Professor reminds the crew that although they're doing the heist for Rio, they're doing it for themselves, as well. While the government may think they have nothing to lose, the notable "robbers" intend to show them quite the opposite.

When He Talks About His Legacy

“I’m A Thief. Son Of A Thief. Brother Of A Thief. I Hope Someday To Be The Father Of A Thief.”

Easily one of the best quotes from Netflix's Money Heist, The Professor perfectly encapsulates the very root of the heists. They have never been about the money. They were about the very art of the plan, redistribution of wealth, and the overall living homage to his deceased father and brother.

Towards the end of the show, The Professor echoes the quote above in a standoff with Tamayo, not only owning his identity but accepting that the heists were for him just as much as they were in honor of his family.

When He Explains That Love Does Not Guarantee Loyalty

"Everyone Is Capable Of Betrayal."

Although subtle and quick, this line is essential to The Professor and his direct line of thinking. While in the middle of a fight with Marseilles about whether or not to go rescue Lisbon from interrogation, The Professor mutters this line to remind fans and himself that love does not guarantee loyalty.

While neither The Professor or Marseilles believe that Lisbon would betray them, The Professor echoes an earlier quote and lesson from Berlin: "Betrayal doesn't depend on how much or deeply you love someone, it depends on the magnitude of the dilemma put in front of you."

When He Lays Down The Facts For Palermo

“This Is War. Act Accordingly.”

Part 4 of the show begins in somewhat of a mad dash to save Nairobi's fleeting life in the middle of Tokyo's coup d'état. In the midst of all the chaos, The Professor tells Palermo that their situation is no longer a heist or an act of defying the system, it has now become war.

The Professor was always adamant to avoid violence and bloodshed for the sake of the purpose and art of the heists, but after falling for the government trap of Lisbon's face execution, all bets are off. Fueled by the unlawful kidnapping and torturing of Rio, The Professor was now sent over the edge with the assumed death of his partner.

When He Explains Why There Can't Be Violence

"If There's A Single Victim, We’ll Stop Being Robin Hoods..."

From the very beginning of the show's five parts, the gang of robbers has owned the title of modern-day "Robin Hoods." Known for "stealing from the rich to give to the poor," the gang did exactly that by extending their fortune to the public.

The Professor, known as the most intelligent of the Money Heist cast, is very clear about their plan and motives from the very first episode of the first season, explaining that the deeper motive behind the heists is rooted in classism, not violence. It was always "vital" to have the public on their side so that they may be seen as heroes instead of villains.

When He Explains That His Death Wouldn't Be The Be-All-End-All

“The Plan Is Devised To Survive Any Setbacks, Even My Death."

If there is anything that can be said of The Professor, it's that he thinks every part of every plan through from A to Z. In one of his most perilous moments of the show, he makes sure that his crew knows that his plan is not only fool-proof but life-proof, ensuring that his death isn't the be-all-end-all.

Not only the crew is notified, but this very quote is said to Alicia Sierra in what could soon be his demise. Even in his most life-threatening moment, however, he assures her that he would never turn on his gang, even if it meant death.

When He Explains How Love Can Cloud One's Judgement

“When Someone Is In Love, They Look Through Rose-Tinted Glasses – Everything’s Wonderful.”

In Part 3, The Professor explains that love is known to cloud even the most focused. He emphasizes the idea that being in love can cause a loss of rationale and logic.

The biggest example of this for The Professor is seen later in the show, when believing that Lisbon had been executed, he fell into a downward spiral. Otherwise objective and level-headed, that sense of motivation fueled by love and revenge almost steers The Professor and the gang wrong, until he realizes Lisbon is still alive.

When He Summarizes The Heist

“It Didn’t All Work Out The Way We Wanted. We’re Not All Here, But We Did Achieve Something.”

With their longest heist finally coming to a close, The Professor delivers a heartfelt speech as the gang finally reunites in the hangar. The camera pans and fans can't help but notice all the missing faces in the crowd, not only from this heist, but from the series' origin, faces like Tokyo, Nairobi, Moscow, Oslo, Berlin.

The scene is such a bittersweet moment for every fan who has followed the group's journey over the last four seasons, growing, loving and mourning alongside them on two of the most thought out and thorough heists ever seen on TV.
