"Supergirl" is getting even more topical with its Season 2 finale title which, if you're up on your politics, will resonate with you.

EW.com reports that season finale is titled "Nevertheless, She Persisted." The title is the feather in the cap of this season, which was rife with tons of themes including immigration, LGBTQ representation, inclusion and more.

But how does this title pertain to the episode at hand? It would seem that it's referencing the gargantuan amount of superhero work Kara Danvers/Supergirl (Melissa Benoist) is going to do before the season is over. Teri Hatcher's Queen Rhea of Daxam has vengeance on her mind after her son Mon-El (Chris Wood) chose to remain on Earth with his Kryptonian girlfriend rather than head home to his rightful place in Daxam's royal family. Zod, played by Mark Gibbon, will make his presence known in the episode, and on top of all of that, the rogue organization Cadmus is still waiting to make its move. Supergirl will have the help of Cat Grant (Calista Flockhart) and Superman (Tyler Hoechlin), but, as the episode's title suggests, she's going to have to persist in order to ensure the safety of National City's residents.

The episode's title connects Supergirl persistence with that of Senator Elizabeth Warren, who refused to be silent during the debate to confirm now-Attorney General Jeff Sessions. Rather than comply with demands that she be silent, Warren read a 1986 letter by the late Coretta Scott King opposing Sessions. However, she was interrupted and ultimately silenced by a vote.

The phrase itself actually comes from Sen. Mitch McConnell's explanation of the vote to silence Warren. "Sen. Warren was giving a lengthy speech. She had appeared to violate the rule," McConnell stated. "She was warned. She was given an explanation. Nevertheless, she persisted." This quote quickly became a rallying cry, acting as a way for women to express how they have been silenced in their lives and how they, too, persisted against opposition at home, at work and in the government. It's appropriate, then, that "Supergirl" would adopt it to close out a politically-charged season.

The "Supergirl" finale will air May 22 at 8 p.m./7 p.m. central on The CW.
