Jane taking charge of her life and transferring her job to Los Angeles so she can confront Bing.
Lizzie's serious declaration that she'll hit Bing in the head with a frying pan if she sees him again.
Charlotte telling Darcy how much she disapproves him no matter how dangerous it is for her professional expectations. This was just impressive.
Lizzie calling Caroline on her bullshit.
"I believe an appropriate response would've been, 'What letter?'"
Charlotte calling out Caroline in Episode 64. And Lizzie revealing Caroline's true self. Caroline is a two-faced manipulative bitch who doesn't believe in true love.
Lizzie blackmailing Mr. Collins into letting Charlotte go home for Thanksgiving.
Jane deciding to move on from her relationship with Bing and embracing her new life in Los Angeles. On top of that, she tries to get her sisters to do the same.
Lizzie subtly (or not so subtly) uninviting Wickham from Lydia's party.
Gigi simultaneously fooling Elizabeth and Darcy so they meet up at Pemberley. In the cutest, most adorkably awesome way ever.
In episode 84, while being interrupted in his attempt to ask Lizzie out, Darcy swoops in on a white horse, buys her a ticket home to save Lydia and makes a dramatic exit that exudes both awesomeness and "Darcy to the rescue!" cheers.
In Gigi's spinoff, she manages to get George to both download Domino and call her on it, so he accepted the terms of service and they've got his info - which means Darcy can find him. Gigi totally saves the day!
Lizzie confronting Bing over how easily he was talked into dumping Jane, with the Setting Update meaning he's not let off the hook nearly as easily. And both her and Jane say they'll kick his ass if he hurts Jane again.
When Bing comes to the house, Jane doesn't rush to see him, and has Lizzie coolly inform him that she'll get back to him. When she eventually does come down, she greets him with a single word: "Hello". From Miss "Oh hi, it's so good to see you!", this is practically a slap in the face.
Episode 98. All of it. Special mention goes to Darcy's smooth "I could use further illumination on certain points, however." And then going in for another Big Damn Kiss with Lizzie.
Q&A #10: Darcy manages to completely fakeout Lizzie but simply walking out with an apology for disturbing her video. She just sits there for a second, stunned and confused. Then he runs back in, grabs her, and carries her back out of the room.
In Episode 99, Lizzie turns down Darcy's job offer, wanting to make a living on her own merits rather than being the woman who's sleeping with the boss.
