The Massive Vaylin Lore-Drop We All Missed
"From the moment his daughter, Vaylin, was born, Valkorion felt her strong connection to the Force. As she grew up, the Immortal Emperor noticed similarities between them, which both pleased and frightened him, and he decided to keep a tight leash on his favorite child. Her father's control curbed her tendencies toward violence and anarchy, but beneath her upbeat and lighthearted exterior lurked a restless hunter, hungry and ambitious. When most of the Emperor's power was locked away on Yavin 4, he was no longer able to hide Vaylin's strength from her, and she finally got a taste of her full capabilities. Instead of striking back, however, she decided to bide her time, like a predator studying her prey. She formed a close bond with her brother Arcann as they both detest the idea of destiny. However, Vaylin isn't one to stay in the shadows forever."

Think of the implications of this codex entry.
It implies that Valkorion - well before sending her to Nathema for 'conditioning' - was suppressing her Force potential.
It further implies that this ceased being an option when the Emperor's Voice was destroyed on Dromund Kaas, sending his spirit (or apparently just his power) into withdrawal on Yavin. This led to the events in the KOTET trailer "Betrayed", and the horrific events of Vaylin's exile to Nathema.
Meaning the actions of the Hero of Tython unintentionally led to Vaylin’s conditioning.
The timeline... doesn't fit perfectly. After all, an adult Vaylin - free of Nathema, albeit "conditioned" - appears at the start of Knights of the Fallen Empire, only about four years after the Dromund Kaas raid. Even if she were only 18 or so at the time, that's still a jump, given what we saw in the trailers. (She doesn’t look 14 when she cripples those Knights.)
But if so, that's a blockbuster in the overall story.
