Blair rages at the headmistress, and through her rants, she finds out that someone from Constance has been accepted to Yale. But who?

There's a new teacher in town, and she doesn't look much older than the students! Ms. Rachel Carr is new to New York after a Teach for America stint in Alabama, and she's just getting to know the lay of the land. Dan and Serena are friendly to her, but Blair isn't. How can she be when she got a B on a paper? She pulls Rachel aside and explains that as a second semester senior, she should be getting a free pass. Blair's face crumples: She needs a perfect GPA to get into Yale! Too bad, says the new teacher. Blair runs to Serena for comfort, and S can't be much of a friend right now, given her big secret.

Lily meets with another shareholder and finds out that only Chuck's guardian (right now, Jack) can control Bass Industries. Just then, Jack enters and faces off with her in a not-so-pleasant way. He doesn't like that she's getting involved in the company.

Chuck and Lily continue to plan how to get Jack out of the way, and it seems like they're making progress... until her phone rings and she takes a rather schmoopy call from Rufus. Chuck is furious and accuses her of caring about no one but herself. He storms out. Lily doesn't say a word to defend herself.

Serena catches Blair and her minions plotting at lunch and she calls them out on it -- are they planning something evil for Teacher Rachel? Serena finally blurts it out -- Blair got into Yale. Serena gave up her spot, so now Blair's in. Since she's in, will she call off Operation Get Rachel, Serena wants to know? Blair sort of agrees, but we find out later that she's still planning on tricking the teacher. And during all this, Dan stands awkwardly on the sidelines, trying to be a part of Serena's life and failing miserably. He's pretty upset that she a) lied about getting in and b) decided NOT to go to Yale without even consulting him. Some relationship! He stalks off.

Nate and Vanessa are strolling along, enjoying each other. He was going to take her to the opera, but she surprises him with tickets first, so he doesn't tell her about his plans. But when they arrive later, Dan spills the beans, asking about the box seat. To appease Vanessa, the couple still sits in the third tier seats, but they're next to an old woman who can't stop coughing, so Vanessa agrees to upgrade. And hey -- they can make out in the box seats! Looks like that class issue was easily resolved.

Blair and her pals decide to trick Rachel after all. She invites her to the opera with no intention of actually meeting her there, and naive Rachel accepts.

At the opera, Lily and Rufus seem to have their kids' lives all planned out for them -- well, more like their vacations, which will revolve around where their kids go to college. Long weekends on the East Coast! Trips from Yale to Brown! It's a little much for Dan and Serena. They take a moment to themselves and discuss their troubles. Besides their parents being all over each other, they're not even communicating anymore. Serena doesn't really think they can get past this, but Dan thinks they can, as long as they compartmentalize this part of their life away.

Lily and Rufus have an awkward confrontation with Jack Bass, who belittles Rufus. Then, after they chat with the Bass family lawyer who knows Lily, she has a flash of brilliance and runs to Chuck with a proposition. She shows him some papers that she and Bart had drawn up before he died about her adopting Chuck. Which would make her his guardian... and therefore take Bass Industries away from Jack. Chuck's all for it, but when Jack sees what's happening, he flips out.

Blair gets a call from the headmistress about Ms. Carr. Turns out Rachel was concerned about Blair and wanted to be sure that she'd still get into Yale in spite of her B. Blair feels awful and decides to go save her teacher from embarrassment, but it's too late. Rachel's not thrilled about this "lesson," and though Blair begs forgiveness, her teacher is not exactly up for a night at the opera. After Blair leaves, Rachel makes a phone call to the headmistress and tells her what Blair did.

Lily takes a powder room break, only to be surprised by Jack! He locks them both inside and confronts her. "I'm not scared of you," she says. "You should be," he says, blocking her path. Scary! Suddenly he throws her against the wall, screaming in her face, and then he tries to kiss her! She fights back, but he's winning...

Rufus and Dan notice that Lily's missing, but they're kind of slow on the uptake. It's Chuck who notices the powder room door is locked, suspects the worst, and bursts in, just in time. He punches Jack out. Then Rufus shows up, too late to do anything but escort her away. But something's changed between Lily and Chuck after this incident.

The next day, Chuck shows up and they discuss Jack's fate (he's on his way back to Sydney). Then she tells him that she knows he'll do wonders with Bass Industries. She's giving it all to him on his eighteenth birthday. All she wants is Chuck, as a part of her family. Chuck is surprised and touched. And then he tells her he knows Bart's death was an accident -- absolving her of the blame and accusations he lumped on her earlier in the episode. And THEN he agrees to move in!

Serena realizes things just aren't going to work with Dan. She calls him, but he must realize something's up, too -- he ignores her call. Just then, Ms. Carr (call her Rachel!) shows up at the Brooklyn cafe. They banter excitedly. Gee, will these two hook up?

Blair has a meeting with the headmistress. She thinks it's going to be about something good, but instead, she gets some really bad news. Turns out Ms. Carr's call to the headmistress means that Blair gets detention! Her Yale acceptance has been put on hold until detention is completed. Blair leaves the office with Dorota, determined to get revenge.
