The reason New Hyrule's stained glass depicts a young Tetra is because Anjean requested its construction a long time ago, and she wished for it to depict the young pirate who was first tasked with building a new kingdom. She wanted to remind Tetra of her true identity - not Princess Zelda. From what she had been told by the Hero of Winds, she believed the late King Daphnes had a similar change of heart in his final moments. (Even if Tetra wasn't so certain...)
Dusk from Twilight Princess is perhaps the Zelda with the strongest connection to Wisdom. Her every action— surrendering to Zant, uncovering the location of the Master Sword, giving the Triforce to Midna— contains a level of rational thought and caution I’ve gotta appreciate.
She also knows what it feels like to be possessed by evil. If that really is Link’s body in that EoW trailer… maybe she (or Phantom!) can relate.
(Edit: In unrelated news; it is also my birthday today! EoW is gonna be a slightly late birthday present to myself 😇)
