Heroes in games have enemies, of course. Enemies use sneaky tricks to trap and harm the heroes - or at least try to. So why shouldn't heroes resort ot the same sorts of trickery and shenanigans to combat their foes?
What? Because they're heroes and shouldn't stoop to such tactics?
Since when has that argument worked with a group of players?
Commentary by memnarch (who has not seen the movie)
Appreciate the Dark Side? That's certainly an unexpected statement. Knowing one's enemy makes sense as well, except that one probably shouldn't become one's enemy to do that. That sounds like a recipe to cause all sorts of problems for one's self. I bet Luke is actually warning Rey about the Dark Side in the movie and how it's tempting, but will cause all kinds of problems.
That's an odd picture of the hands I have to say. If either the comic or my guess is accurate to the movie, I don't know why that would be included. Perhaps it's sort of like training wheels? Movie Luke might be able to tell that Rey has the potential for using the Force, but not the courage or something to use it whenever. So he'll levitate the rock, tell her what to do to do it herself, and just stop to let Rey find she's holding herself up. And then possibly drop the rock right after if the movie needs a bit of levity.
And for true villainy, I'm pretty sure hair, big or small, isn't necessary. I'm also pretty sure biology isn't necessary either. Though since technically Nute did start out as a biological being, perhaps that's needed at some point.
BB-8: We can’t do much more until we get to Canto Bight.
GM: Okay. Let’s switch back to Luke and Rey.
Luke: Close your eyes. We need to train you to discern the Dark Side. Really feel it. Appreciate it.
Rey: To access its power? Cool.
Luke: No. Know thy self. Know thy enemy.
Luke: Learn its tricks. To perceive and penetrate them.
Luke: To know your enemy, you must become your enemy.
Rey: Can I avoid the big hair?
Luke: The hair may be necessary for true villainy.
