Elizabeth went to Pemberley, and when there, discovered Darcy in bed with Bingley. Realizing why Bingley actually broke her and Jane up, she was saddened, because she never stood a chance. Then she got mad - Darcy proposed to her, expecting her to live her whole life with a gay dude? No. That asshole. She took the revolver from her hip and shot him. Bingley, horrified at the death of his best friend - and lover, it seemed - cried. Lizzy, gone completely insane with menstruation, just laughed. Suddenly, Caroline walked in the room - Lizzy beat her to death with her shoe.
She left, revolver in her hand, and went to find Lydia in Brighton. She was being raped by at least seven officers. Deciding this was was not punishment, but pleasure, to Lydia, she shot all of the officers. Lydia was so happy she was being used by officers she just lied there, not noticing, until she died of thirst. (Kitty, receiving news of this later, as always, followed Lydia's lead, and just lied down in her bed and, too, died of thirst.)
Then she went to Rosings. She put the gun down for a moment, and picking Lady Catherine up by the throat with one hand, she walked into Mr. Collin's estate. She strangled him to death with the other. Charlotte walked in on this, and wailed in horror. Lizzy tied her to a bedpost with nearby rope, so her hands were indisposed. She threw Collins on top of her - she never should have married him - and then Lady Catherine on top of him, his true love.
Going to Longbourn, she shot her mother for being such an idiotic bitch. Then she threw a book case on top of Mary, crushing her to death. Her father, an idiot for marrying her mother, but a tolerable man, she only shot in the knee.
After sending a letter to Wickham, filled with a page on which she only wrote "jackass," and some anthrax, she asked Jane, totally ignorant of the goings on, to tea.
"Of course, my dearest sister."
