Gary does have telekinesis. He moved a cup via his mind and turned on a sink and called the cup to his hands.
In the episode, we only seen him do somethings but it is possible he was able to create a lightsaber, very possible. he was able to see things partially before they happen, similiar to a Jedi's danger sense. this would give him the oppurtunity to block incoming strikes from Luke.
it was also rumored he was partially empathic aswell
Locked since Kirk here can't tell the diffrence between reply and new-topic.
