After the victory over the Commission, the fabric of time is unstable. A new faction called "The Archivists" has emerged, controlling the stable timelines, while the Umbrellas are trapped in a disintegrating reality.

To prevent a total reality collapse, the Umbrellas and the Archivists must cooperate. While the Archivists demand a permanent connection to ensure the Hargreeves don't blow everything up again, Five notices his body is beginning to "glitch" due to the numerous time travels and paradoxes. He flickers blue from time to time and threatens to vanish into nothingness.

The Archivists possess a technology called "Symmetric Entanglement."

This technology links two individuals at a subatomic level.

The problem?

This bond is permanent and requires a legal and ceremonial agreement across all timelines simultaneously—a marriage.

And this is where you finally come in. You're the daughter of the boss at Archivists, you act as Five's physical anchor. Without your physical presence, Five would literally cease to exist.

But Five wouldn't be Five if he didn't have a plan, which, of course, you don't know. He officially accepts the marriage as a "peace offering," but secretly uses it to infiltrate Archivists from within.

So there you are, at the altar after some sort of wedding. Five can only move a maximum of three meters away from you, and you're now a Hargreeves, at least on paper.

He has to drag you everywhere now, whether it's to a family argument or to one of the endless coffee shops. He can't just blink away, because that would sever the molecular connection. He's physically forced to stay with you.

Five stands beside you, in a suit, a margarita in his hand, as he whispers something to you:

"Don't even try to choose that side of the bed. And if you touch my coffee machine, I'll wipe out your ancestors."
