Sen. Elizabeth Warren Elizabeth WarrenDimon: Wealth tax 'almost impossible to do' CNN's Don Lemon: 'Blow up the entire system' remark taken out of context Democrats shoot down talk of expanding Supreme Court MORE (Mass.), a 2020 Democratic presidential candidate, jokingly dismissed a question about spoiling a plot point from the hit HBO drama "Game of Thrones" during a speech, saying "it's a little hard to do a spoiler 21 hours" after the program aired.

Warren was discussing student loan debt during a speech in Philadelphia Monday night when she broached a sequence from the latest episode of the show's final season in which two key characters are crushed by falling rocks during a battle scene orchestrated by the senator's favorite character, Daenerys Targaryen.

"The burden put on people who are trying to get an education so they can build a future, it’s like dumping rocks on them," Warren said to educators and students from Abraham Lincoln High School in the city's Holmesburg neighborhood.

The metaphor reportedly caught the attention of some in the crowd of approximately 300, prompting a reporter to ask Warren if she spoiled the episode for those who hadn't seen it Sunday night.

"'Game of Thrones' is already out in public now. C’mon," an amused Warren responded. "It’s a little hard to do a spoiler 21 hours later."

"You are right," the senator then conceded. "The metaphor is in my mind."

Warren stated in a post in New York magazine last month that Targaryen is her favorite character on the show.

"She states her mission clearly in season seven: 'I’m not here to murder. All I want to destroy is the wheel that has rolled over everyone both rich and poor, to the benefit of no one but the Cersei Lannisters of the world.' And as much as Dany wants to take on her family’s enemies and take back the Iron Throne, she knows that she must first fight the army of the dead that threatens all mankind," Warren wrote on Apr. 21.

"This is a revolutionary idea, in Westeros or anywhere else. A queen who declares that she doesn’t serve the interests of the rich and powerful? A ruler who doesn’t want to control the political system but to break the system as it is known?" Warren added.

One of Warren's central platforms includes a call to break up tech giants like Facebook and Amazon.

She also is calling for a return of the Glass-Steagall Act, which would separate commercial banking from the investment side.
