WandaVision

[The two Visions' battle takes them into the Westview library]

Hex Vision:
Why are you doing this?

White Vision:
My programming directive is to "destroy the Vision".

[Their fight progresses, until Hex Vision gets White Vision in a chokehold]

Hex Vision:
But I'm not the true Vision. Only a conditional Vision.

[White Vision phases out of the chokehold. Hex Vision heats up the laser in his forehead, prepared to fire, but White Vision doesn't do the same]

White Vision:
I request elaboration.

[The two Visions float around the rotunda in the center of the library]

Hex Vision:
You are familiar with the thought experiment the Ship of Theseus in the field of identity metaphysics?

White Vision:
Naturally. The Ship of Theseus is an artifact in a museum. Over time, its planks of wood rot and are replaced with new planks. When no original plank remains, is it still the Ship of Theseus?

Hex Vision:
Secondly, if those removed planks are restored and reassembled, free of the rot, is that the Ship of Theseus?

White Vision:
[frowns] Neither is the true ship. Both are the true ship.

Hex Vision:
Well, then, we are agreed.

White Vision:
But I do not have the Mind Stone.

Hex Vision:
And I do not have one single ounce of original material. Perhaps, the rot is the memories. The wear and tear are the voyages. The wood touched by Theseus himself.

White Vision:
I have not retained memories.

Hex Vision:
But you do have the data. It is merely being kept from you.

White Vision:
A weapon to be more easily controlled. But, certainly, you are the true Vision, for you believe yourself to be.

Hex Vision:
That was once the case. But upon meeting you, I have been disabused of that notion.
