Well, lightsaber crystals reflect the will of those atuned to them. An individual can meditate to bond with one, increasing its connection. But I wonder if that bond can be reversed, or even caused to react negatively, through the forceful application of the Force...
It may be, but I mean, a lightsaber is just another weapon, another item. If they can do it to a blaster being fired at them, it could probably be done to a lightsaber being swung at them.
For one, my character Alexandra could probably take an enemy's saber apart in her mind, because she is much more advanced, (dont ask) and for two, The father, or Vader in German, took his son's hand that was holding the father's or Anakin's lightsaber.
