This unnamed girl is the granddaughter of Lisa Simpson sixty years in the future, as seen in "It's a Blunderful Life".
History[]
At some point in time prior to the events of "It's a Blunderful Life", Zia Simpson gave birth to this girl, making Lisa a grandmother.
During Thanksgiving, the granddaughter asks Lisa why they have to remember to light a candle every holiday, before Lisa recounts the story of the blackout that almost destroyed Springfield days before Thanksgiving.
Physical appearance[]
The girl heavily resembles Lisa when she was an eight-year-old, although her hair is slightly ruffled and longer. She wears a light purple T-shirt with a pocket on the left side.
Trivia[]
- In Holidays of Future Passed", it's mentioned that Zia was made from only the "best genetic material" (i.e. Lisa's DNA and none of Milhouse's), so it's entirely possible that Lisa's granddaughter was also created rather than conceived, which would explain why there is no father present at the dinner table. However, there is no mother present for Bart's grandson possibly meaning the parent is dead or somewhere else
