This page discusses the Season 4 finale in full: who the series says committed the killings, Emma's exit, Maggie's return, and the last Aileen Wuornos scene. Episode 8 recaps the hour; this page is the argument.
Show the ending
The short version
The show depicts Lizzie Borden and Bridget “Maggie” Sullivan as the killers of Abby and Andrew Borden. Lizzie is still acquitted — that part is history. After the trial, Emma leaves Maplecroft. Maggie comes back through the front door. The series gives them a later life together as partners and suffragists. The last image is invented: after Aileen Wuornos is executed, Lizzie and Maggie meet her in a constructed afterlife and tell her that all is forgiven.
Did she do it?
Two answers sit on the same page, and they are not the same kind of fact.
The series: earlier hours already showed the plan, the axe, and the cleanup. Carnival does not reopen that question. It assumes the audience has watched Lizzie and Maggie do it, then asks what an acquittal is worth once the town has turned the case into a costume and a rhyme.
The record: on June 20, 1893, a New Bedford jury acquitted Lizzie Borden of both killings after a short deliberation. No one else was charged. The case is still legally unsolved. The jump-rope verse that assigns forty and forty-one blows is folklore; its counts do not match the wounds, and it presumes a guilt the jury declined to find.
What happens after the verdict
The hour jumps forward. Lizzie has money and a house the show treats as Maplecroft — historically the Fall River home she and Emma moved to after the trial. She uses Lizbeth, a later name the real Lizzie Borden did prefer. The house is staged as the opposite of Second Street. The town still wants a killer named. Halloween brings a child dressed as her. A bookstore will not stop selling the legend.
Emma will not die there. She leaves so the house does not become the rest of her life, and she hopes the truth is someday admitted. Maggie, sent away to a husband the series treats as another trap, reaches for an axe, stops, and comes back. She walks in the front door. Lizzie prays for a forgiveness she did not ask the jury for. The two of them are then shown campaigning for the vote and hosting the celebration when it arrives.
Maplecroft and the later estrangement from Emma have a historical spine. The partnership, the suffrage second act, and the deathbed hope are dramatization. The Episode 8 recap walks the hour beat by beat; the 1892 timeline keeps the documented case without the series' answer.
The record's Maggie has her own page: what Bridget Sullivan actually did after the trial — the testimony, the Montana years, and a silence the series replaces with a second act.
Why the last scene is Wuornos
Sarah Paulson's thread begins earlier in the season, including a later-era visit to the Borden house after it has become a bed-and-breakfast. Aileen Wuornos was a real person, executed in Florida in 2002. She has no documented connection to the 1892 household. The series uses her as the other end of a question Ian Brennan has said the anthology keeps asking: whether a “monster” is born or made.
Carnival gives her a trial and a lethal injection. In the constructed last image she opens her eyes and finds Lizzie and Maggie waiting to take her somewhere safe. “All is forgiven. All is understood.” Then the gallery curtain closes on the actual execution. In a post-premiere interview, Ian Brennan described the coda as an attempt to imagine some peace for these women, while Netflix Tudum's ending interview presents Lizzie's resolution as happy and Wuornos' as not escaping consequences. Those are the creators' readings of the drama, not evidence about 1892 or 2002.

Show vs. the 1893 record
| Question | The series | The record |
|---|---|---|
| Did she do it? | Earlier episodes depict Lizzie and Maggie as the killers. Carnival treats that as settled. | Acquitted June 20, 1893. No one else charged. Still legally unsolved. |
| Where does she live afterward? | A new house staged as Maplecroft — animals, orchard, a place nothing should fear. The town still treats her as the rhyme. | Lizzie and Emma did move to a Fall River house later called Maplecroft. Lizzie died there in 1927. |
| Emma | Leaves so she will not die inside the legend; hopes the truth is admitted someday. | The sisters later became estranged. The farewell speech is dramatization. |
| Maggie / Bridget Sullivan | Returns through the front door, stays, and shares a later life as partner and suffragist. | No reliable record that Bridget Sullivan lived that second act with Lizzie. |
| Aileen Wuornos | Executed, then met by Lizzie and Maggie: “All is forgiven. All is understood.” | Real person, executed in Florida in 2002. No documented connection to the Bordens. |
Direct answers
Did Lizzie kill her parents in Monster: The Lizzie Borden Story?
On screen, yes: the series depicts Lizzie Borden and Bridget “Maggie” Sullivan as the killers of Abby and Andrew Borden. That is a dramatic choice. The 1893 jury acquitted Lizzie, no one else was charged, and the real case remains legally unsolved.
How does Monster Season 4 end?
After the acquittal, Emma leaves Maplecroft. Maggie returns and stays. The series gives Lizzie and Maggie a later life as partners and suffragists. The last image is invented: after Aileen Wuornos is executed, Lizzie and Maggie meet her and say that all is forgiven.
What happens to Maggie in the finale?
The show sends Bridget “Maggie” Sullivan away to a husband, then has her refuse that life and walk back into Lizzie's house through the front door. They stay together. Historically, there is no reliable record of that second act.
What happens to Emma Borden?
In Carnival, Emma refuses to keep living inside the legend and leaves, hoping the truth is someday admitted. The sisters did later become estranged in real life; the deathbed line is the series.
Why is Aileen Wuornos in the ending?
Sarah Paulson's Wuornos thread is a later-century invention with no documented link to the 1892 household. The series uses her execution, and a constructed meeting with Lizzie and Maggie, to close the anthology question of whether a “monster” is born or made. The Aileen Wuornos guide on this site walks through every scene she appears in.
What not to take from the finale
- The series' on-screen confession is not a newly discovered fact about 1892. It is a dramatic choice.
- The jump-rope rhyme is still folklore. Its body counts are wrong, and it presumes a guilt the jury did not find.
- Wuornos meeting Lizzie is fiction. Do not repeat it as biography of either woman.
