In the time space, Amelia, Anton, and Azrael emerge from Lisavet Levy’s last living memory and stand near the chasm. Amelia realizes the chasm exists because Lisavet repeatedly rewrote the past to hide and protect her, and Amelia struggles to reconcile that sacrifice with the violent, coercive “Moira” she has known. Anton, devastated, fixates on the fact that his father fought for Lisavet his whole life and that Lisavet killed him; he pulls away and asks to be alone.

Elsewhere in 1965, Moira wakes to find Ernest still working late on theories meant to permanently cut off access to the time space. Their relationship is tense and mistrustful: Ernest carries competing images of her (Lisavet, Jack’s secretary, and the TRP director who opposed his rebellion), and he even locks the bedroom door. On the fire escape, they talk more honestly—Ernest admits he wants to forgive her but can’t reconcile everything, and Moira admits she doubts whether sealing the time space is possible or wise.

Ernest then shares a new line of thinking: Elaina’s memories are missing from the time space, and he suspects the chasm may be more than a wound—possibly a passage to alternative histories created when memories and timelines are altered. He argues that consciousness and memory behave like conserved energy, and that destroying or imprisoning memories may redirect them into places like the chasm. Moira grows alarmed as she realizes Ernest is considering making another massive change to the past to open the chasm further.

After they eat, Moira secretly reads Ernest’s black notebook and confronts him in the bedroom: he has been planning to act without telling her. Ernest admits he intends to do it, believing it is the only way to ensure no one can ever control the time space again, even though it would trap him forever. Moira argues that Amelia would be left without him and that Moira herself could be imperiled, but Ernest insists Amelia is more untethered from Time and would persist; when Moira offers to do it instead, Ernest refuses, terrified of losing her again. He agrees to keep looking for another solution, but he will not promise to stop.

That night, Moira senses urgency as they sleep together, then wakes after midnight to a door closing. Ernest is gone, a watch is missing from the open box, and Moira grabs her revolver and a coat (with her father’s watch in its pocket) before winding her own watch and entering the time space to follow. There, Amelia hears footsteps and is shocked to find Uncle Ernest arrive in person; he holds her as she sobs, says he came to get her out and that it is “almost” over, and stiffens when Amelia says Azrael showed her everything. As Amelia clings to him and begs him not to leave again, Ernest asks a pointed question: where is Anton?
