But that’s the ‘real’ version of what happened. If you delete it, there’s only the two less accurate recollections, though I suppose that would add an interesting amount of additional ambiguity. I have seen a tweak to it here (though I don’t recall who by, sorry) where it was adjusted to have Luke explicitly turn his saber off before Ben struck at him, making it clearer that Luke wasn’t going to attack him, which might be the sort of thing you’re looking for.
If I remember correctly that was an idea put forward in the ST Radical Redux thread. I know someone started working on it, but I don’t know if they ever finished it. (I hope they did/do, though!)
That was me
Not very impressive, you don’t ever see the blade actually retract, but if I made a fanedit of TLJ I’d be satisfied. If OP or anyone else finds this interesting they’re welcome to use it, I’ll render a higher bitrate version.
