For all intents and purposes, cementing her status as Queen Bee, not only to Constance but the entire Upper East Side.
It's difficult to say which of Blair's many takedowns is the best. She was often cruel, but she was also right, most of the time. What's more, she always knew exactly how to burn her victims, and she always did it with a smile on her face.
"You Mean He Dumped You Because He Found Out You Were Satan?"
During the first season finale, Blair and Chuck team up to deal with the problematic Georgina Sparks. They send her to a military boot camp for troubled girls, but Georgie returns in season 2, seemingly reformed after finding religion. It isn't long before she's back to her old ways, and this time, Blair is at the top of her revenge list.
Georgina arranges to be Blair's roommate at NYU, going out of her way to ruin the young Waldorf's life. She claims she's still into religion, and she and Jesus "redefined" their relationship, prompting Blair to give one of her classic and witty comebacks.
"Signs Are For The Religious, The Superstitious, And The Lower Class."
"Last Tango, Then Paris" is one of the show's most memorable episodes. It features Blair and Chuck's break-up after he sleeps with Jenny and ends in a cliffhanger, with Chuck shot and seemingly bleeding to death on the streets of Prague.
Earlier in the episode, Blair and Dan meet by chance. Blair is still struggling with whether or not she should meet Chuck atop the Empire State Building, and Dan is unwillingly helpful. He talks about signs and how they are there for a reason, but Blair says she doesn't believe in them. Except, she kind of does, and even she its it by the end of their brief interaction.
"You Are Living Proof That A Person Can't Buy Class."
Speaking of Chuck, Blair's story isn't complete without him, for better or worse. During season 2, they play an overly long and tedious game of will-they-won't-they, culminating in them finally getting together. However, the entire season goes by before that happens.
During the first few episodes, Blair dates a Lord, and Chuck goes out of his way to separate them. During one of her parties, Chuck shows up and seduces her, wanting to spend the night with her. She rejects him, telling him he's "living proof that a person can't buy class." Chuck is the wealthiest character on the show, by far, but she might be on to something.
"Do You Have Any Idea Of The Psychological Torture I Have Endured Being Nice To You?"
Nelly Yuki is one of Blair's main rivals at Constance. She eventually becomes one of the minions, but their rivalry continues into adulthood.
During season 6, Blair attempts to run Waldorf Designs and learns that Nelly Yuki is the reporter for Women's Wear Daily. Old habits die hard, and the two once again engage in petty games, with Blair trying to sabotage her way to the top. Eleanor tries to mend the relationship between the two girls, but Blair, instead, chooses to try and blackmail Nelly into compliance. She even insults Nelly by implying that spending time with her is torture, making things worse.
"Once Men Have Tasted Caviar, It Baffles Me How They Settle For Catfish."
Juliet Sharp arrives in season 4 and quickly becomes one of the show's most dangerous antagonists. She succeeds in ruining Serena's life by getting her kicked out of Columbia and into a rehab center.
Before all that happens, she starts her vendetta by dating Nate and turning him against Serena. Nate falls under Juliet's charms almost immediately, still hurt by Serena's treatment of him the previous season. Blair then states her confusion and disgust at Nate and Juliet's relationship.
"Your Deductive Reasoning Skills Are Perfect For A Place Like Brown."
During the first two seasons, Blair's ambition is to attend Yale. She harbors an almost obsessive desire to get into the prestigious Ivy League school, and she seems unstoppable in her pursuit of New Have glory. On the contrary, Serena wants to attend Brown, and during one of their many fights, Blair makes her opinion on that choice very clear.
She mocks Serena's intellect, stating that Brown is the perfect place for her. Serena insists that Brown is an Ivy League School, but Blair remains unconvinced. She goes so far as to describe Brown as "an enclave of trustafarians and children of celebrities who major in drum circles and semiotics."
"Princeton Is A Trade School. There Is Only Yale."
And speaking of Ivy Leagues, Blair also has some controversial views about the other schools. When her chances of attending Yale get jeopardized, Serena tries to calm Blair, telling her there are other options. "There are other schools besides Yale, like Princeton," she naively says, but Blair is not having it.
In reality, any high schooler would give everything to attend Princeton. But, Blair being Blair isn't willing to settle for anything less than her top choice, and she ends up paying the price for her stubbornness.
"Some People Are Simply Better Than Others."
This quote pretty much sums up Blair's character and way of thinking. She believes she's better than others because of her wealth, beauty, and unstoppable ambition, a notion ed by the army of sycophants around her.
Blair is formidable and quite intelligent. She's also resourceful, determined, and creative -- a true visionary in every sense of the word. However, Blair isn't inherently better than anyone else. It's undeniable that she makes the most out of the many opportunities that come her way, but she could use more empathy in her life.
"Once Again The World Has Proven. Anything You Can Do, I Can Do Better."
Blair's minions are always there to obey her. She never treats them with respect, but they don't seem to care. They don't like it, and sometimes they show outright dislike for her ways, but they never say anything because they both fear and ire her.
During her season 2 quest to bring down the new teacher, Miss Carr, Blair sends her minions to deal with the issue. However, she soon finds a way to deal with it herself and makes sure to let her minions know how incompetent they are and how fabulous she is.
