While flipping through Bennett’s chart, Echo mentions that she ‘could kill you with her brain’. This was also said of River in Firefly – both characters are played by Summer Glau.

The episode starts with Echo retelling the events of The Attic to her friends and recalling Clyde’s mention of Caroline having seen the other cofounder of Rossum.

Topher learns that his design for a universal wipe that was given to Rossum by Adelle in Meet Jane Doe will most likely cause the end of the civilization. As seen in Epitaph One, this will indeed happen.

Echo notices Paul is different and later learns Topher had to erase their emotional connection as a way to make his brain function again. Paul was rendered braindead by Alpha in A Love Supreme and Topher found a way to bring him back with Ivy’s help in The Attic.

Echo watches the same tape of Caroline Alpha sent to Paul in True Believer.

While wondering who took Caroline’s wedge, Topher recalls the time Harding was running the house, as seen in Meet Jane Doe.

Topher is still infatuated with Bennett since their meeting in The Left Hand and awkward because of what happened between them later. They discuss those events several times throughout the episode.

November is brought back to the L.A. Dollhouse after being left in the D.C. Dollhouse in The Left Hand. Paul recalls meeting her as Madeline for the last time in The Public Eye.

Bennett and Topher’s task in this episode is to restore the backup of Caroline’s original personality which was damaged by Alpha in Omega.

Claire Saunders returns after her departure in Vows. She is shown to be dating and possibly living with Boyd, which explains his mentions of “things at home” in The Attic.

Whiskey appears in a flashback with the original Dr. Saunders, like in Omega.

The flashbacks show Dominic still working as head of security for the L.A. Dollhouse. He was exposed as a mole for the NSA and sent to the Attic in A Spy in the House of Love; in that episode Adelle also mentions he’d been working with her for three years.

Echo feels like nobody thinks of her as a real person, something she blamed Paul for in Meet Jane Doe.

Echo tries giving Anthony and Priya an out, like she already did in Stop-Loss.

Dominic’s objections to being sent back to the Attic explain his resentment towards Adelle in a flashback from Epitaph One set after his final release.

November has been reimprinted as Paul’s former neighbour Mellie. This persona was introduced in The Target and last seen in Briar Rose.

After Boyd shoots Ambrose, Adelle mentions Rossum board members, including Ambrose, being imprinted in several bodies. In a flashback/memory from Epitaph One, Ambrose was delivered to several Dollhouses and imprinted in several Actives at once, only some of which (such as Victor) were later reclaimed by the houses and wiped.

The good-bye between Boyd and Dr. Saunders is the same scene from Epitaph One.

One of Rossum’s hitmen shoots through a window, shattering it and prompting Adelle to note how she just had it replaced. This is the same window Echo and Alpha fell through while fighting in A Love Supreme.

In The Attic Clyde Randolph told about his partner creating a servile persona based on him, Clyde 2.0. In this episode’s final flashback Caroline meets an Active imprinted as him.

Despite having been given an out by Echo, Anthony and Priya will return to the Dollhouse and rejoin their friends in The Hollow Men.

Adelle mentions Rossum board members being imprinted in several bodies. In Epitaph Two: Return Ambrose and Harding will continue living through imprinted bodies and backups.
