The OT doesn’t establish that Vader can “read minds”. It’s actually the opposite with Vader having to resort to torture to find out information others have.
So, my theory of what’s going on in the OT is supported by what we see in the OT movies.
It was established that Vader could read minds in ANH. The Mind probe is a Jedi ability to go through peoples minds in order to get useful information. That’s pretty much reading someone’s mind right there. Vader even said in ANH that “Her resistance to the mind probe is considerable” . And he wasn’t talking about the interrogator droid either. that ability was established in the OT. Just because he didn’t just read everyones mind doesn’t mean to say he couldn’t do it. We have seen Jedi have abilities then just don’t use them when they really could do with using them ( jedi speed run, super jump, mind control etc etc) .
Yes but some of the abilities you cited first appeared in the prequels and were criticized for creating “plot holes” in the OT where there wasn’t any, just like it’s being done now. And isn’t ‘probe’ a word for robot?
