Query

I intend to use this thread to understand some actions/techniques that I am not able to (yet).

So starting with this:

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.

Taken from Knights of the Fallen Empire

What was Valkorion actually doing in this case? What technique?

Probably using telepathy.

It could be Force Suppression, but it might also be him affecting her through their Force bond. Or perhaps it's something mental?

Almost certainly Force Suppression.

Sounds like Force Molestation to me

Valkorion isn't Sheev.

He was. 🙂

No point in pedophilia when you have no emotion.
