The House of Mirth
Eventually, Lily Bart receives a ten-thousand-dollar inheritance from her Aunt Peniston, which she arranges to use to repay Gus Trenor. Distraught by her misfortunes, Lily has by this time begun regularly using a sleeping draught of chloral hydrate to escape the pain of poverty and social ostracism. Once she has repaid all her debts, Lily takes an overdose of the sleeping draught and dies; perhaps it is suicide, perhaps an accident. That very morning, Lawrence Selden arrives to her quarters, to finally propose marriage, but finds Lily Bart dead. Among her belongings are receipts for her payments toward the debt she owed to Gus Trenor, proving that her financial dealings with Trenor were honorable and not evidence of an improper relationship. His realization allows him to feel sympathy and closeness for her, and he is clearly distraught by her death.
Treehouse of Horror XX
In a parody of "Strangers on a Train", Lisa wants revenge after being sent to detention by Ms. Hoover for disrupting class as she claims another student topped her through a tutor. Bart hatches a "criss-cross" plan and tells Lisa that if she pulls a "ding-dong ditch" on Mrs. Krabappel, he will do the same to Ms. Hoover. Lisa thinks this means ringing the bell at Mrs. Krabappel's apartment and leaving. However, Lisa soon learns that Bart meant for her to kill Mrs. Krabappel (and dump the corpse in a ditch), as he has killed Ms. Hoover. Bart attempts to coax Lisa into killing Mrs. Krabappel with a paper cutter, but she refuses. Eventually, Bart decides to blackmail her into it with help from Willie, who would frame Lisa for the decapitated Skinner to honor his side of the "criss-cross" in which Bart killed Skinner. Realizing that Bart would frame her for these incidents, Lisa tricks him into believing that she was submitting at his will only to get a knife from his hands and attempts to kill Bart in self-defense, beginning a chase sequence. Bart finally finds shelter at a crowded playground carousel, but is left at Lisa's mercy when the other children leave to get ice cream. Lisa, however, recognizing that she would not be better than Bart, says she will never be a murderer, and attempts to throw the knife away. The knife cycles out of control and ends up nailing Bart in the head just as Mrs. Krabappel appears, pleased at his death. Despite her shock for accidentally killing Bart, Lisa agrees that it is better this way and she and Krabappel walk away smiling, leaving the murdered Bart to spin around on the carousel.
