The episode "Bartless" begins with Bart Simpson reading a storybook to Riley in the Springfield library. As he narrates a humorous story about where milk comes from, Bart draws in the book. Other children copy him and start drawing in several library books, causing damage. Marge and Homer take turns scolding Bart for being an unbearable kid.

Next, Marge and Homer visit Springfield Elementary School, where they encounter angry parents upset about Bart's prank. However, the school principal reveals that Bart's prank has actually made the kids more engaged and participative in class. This revelation causes Marge and Homer to feel guilty and wish they could have a normal relationship with Bart, as if he were never part of their family.

Suddenly, their wish is mysteriously granted. They wake up in a fancy house where Bart does not exist. In this alternate reality, Marge is a busy doctor and Homer works as the Jumbotron operator at the Springfield Isotopes baseball stadium. While driving home, the Simpsons encounter a boy who looks like Bart but has no memory of being their son.

The Simpsons decide to take this amnesiac Bart into their home. Bart, who is not originally part of their family in this reality, enjoys spending time with them. His presence begins to change the lives of the Simpsons for the better, bringing new dynamics and experiences to the family.

Throughout the episode, the story follows the interactions between the Simpsons and this version of Bart, showing how their lives differ without the original Bart and how the new Bart influences them.

The overall narrative explores the impact of Bart's character on the family and Springfield, framed by the fantasy of a world without him and the eventual acceptance of his role in their lives.

At the end of "Bartless," Homer and Marge find themselves in a reality where Bart was never born. They discover an amnesiac Bart living separately, and when they bring him into their family, his presence positively changes their lives. The episode closes with the Simpsons reunited, having gained a new appreciation for Bart's impact on their family.

Expanded narrative of the ending scene by scene:

The episode culminates with Homer and Marge waking up in an alternate reality where Bart does not exist. In this world, Marge is a busy doctor, and Homer works as a Jumbotron operator at the Isotope Stadium. They live in a fancy house but feel something is missing.

While driving home, they encounter a boy named Bart who has no memory of being part of their family. This Bart is unaware of his true identity and background. The Simpsons decide to take him home, welcoming him into their family despite the strangeness of the situation.

Bart, now living with the Simpsons, begins to enjoy his new life with them. His presence brings unexpected joy and liveliness to the household, which had felt dull and disconnected without him.

Throughout these final moments, the episode shows how Bart's mischievous and spirited nature, though challenging at times, is integral to the family's dynamic and happiness.

The episode closes with the family reunited, highlighting that despite Bart's pranks and troublemaking, he is a vital and beloved member of the Simpsons. Homer and Marge's journey through the alternate reality leads them to a renewed appreciation for their son and the unique role he plays in their lives.

In terms of character fate at the end:

• Bart is reintegrated into the family, his amnesia resolved by their acceptance and care.

• Homer and Marge return to their original lives, now with a deeper understanding and affection for Bart.

• Other family members, such as Lisa and Maggie, remain part of the household, implicitly unchanged but benefiting from the restored family unity.

This ending emphasizes the importance of family bonds and accepting each member's quirks, showing that even a "Bartless" life lacks the fullness that Bart brings to the Simpsons household.
