Echo Vision Frequency

[MrThinker]

It's not concrete, of course, but she can control when she activates her Resonance. She chooses to activate it in our presence, in response to us having one of her past and then goading her with it. She does this, in spite of knowing that she will most likely have a vision, so it follows that her intent was to view our past. Maybe she can't control the vision trigger, but her Echo does have an on and off switch.

I'm pretty sure that there is a scene in 4.1 where we discuss the Resonant with Alphinaud and he comes to the conclusion that Fordola cannot control the visions, because she had Krile's Echo copied.

As for others who have seen our past via the Echo, it is implied Ardbert and the other warriors experienced an echo of our past at the same time we had an Echo of their defeat of Mitron in our first encounter. Ardbert does the classic head grab we do at any rate.

EDIT: Also, I was under the impression that the Resonant, being an artificial Echo, held the same drawbacks of not being able to consciously draw upon it without training or experience.
