Yeah, I don’t think it could be made explicit, but it is possible Luke could’ve warned them of what he saw. I think Luke warning Han and Leia of their fate at the hands of their own son could add an interesting layer to their actions in the films. I can imagine Leia would refuse to accept it, but I could see that being a factor in Han’s decision to go off and run away from his responsibilities. Maybe he felt he was endangering Leia, or his son’s soul, or maybe it was just a selfish decision. But the idea that Han knows what is going to happen when he confronts his son, but does it anyway, is kind of an interesting idea.
I do think seeing flashes of Han and Leia’s deaths seems like a good motivating factor for Luke. But I do like the idea of the last shot be of Kylo striking down toward camera because I think it would be an interesting approach to frame this vision as being almost lifelike for Luke in that moment. It would demonstrate Luke’s powerful connection to the Force, but also how it can be a curse. The timeless nature of the Force blurs the line between present and future.
It would require some vfx, but it would be cool if as Luke gets deeper in the vision, the hut begins to look like it is being consumed in flames all around him. Maybe you could add embers in the foreground/background, or even show a reflection of flames or Kylo’s red saber in Luke’s eyes. But then when he ignites his own blade, the flames and saber are extinguished, and he snaps back to reality. I think the vision could work as quick, incongruous shots, just like the vision sequence at the beginning of TROS. It’s disorienting (in a good way), but you do get quick glimpses of Han’s death and other moments. You could replicate this with very quick frames of fire, violence and death related to Kylo Ren. Maybe even some quick shots of Anakin/Vader for the parallels. But keep the frame # of each shot similar to the TROS vision. You could also occasionally cut back to Luke in a way that disrupts continuity to further reflect the disorientation Luke is experiencing. In some shots Luke could be surrounded by flames, others not. Maybe you could even have a quick shot of him reaching for his saber while he is still in the throes of the vision, losing awareness that his sleeping nephew is front of him and not the dark warrior he sees. It’s intense, overwhelming and Luke just wants to stop it.
Building off of this a little, this reminds me of a little thing I would like to add to Kylo’s version of the story: At the end of Kylo’s flashback, when it cuts to black after the hut collapses on him and Luke, we get some quick voiceover lines of the other students’ reactions.
Student 1: He killed Master Luke!
Student 2: Kill him!
Ben: No!!!
Sounds of sabers igniting and clashing.
This paints a picture of Kylo believing that he was defending himself from the beginning. I think this would make Kylo more sympathetic and compelling as an antagonist.
And the films don’t really do a great job of explaining why Kylo even fell to the dark side. I’ve said this multiple times, but I like the idea of giving Kylo a vision in TFA when he speaks to Vader’s mask. This convo gave me an additional idea for it though:
Kylo has a vision that paints a picture of his philosophy based on a twisted interpretation of Vader’s life. Democracy and the Jedi lead to chaos. Only order can bring peace to the galaxy. And you must sacrifice the ones you love to achieve that power. Over a quick-flash vision montage you could have lines like:
Palpatine: If the Jedi are not destroyed… civil war without end.
Quick shots of the Clone Wars and the Galactic Civil War ravaging the galaxy.
Sidious: Make the sacrifice!
Quick shots of Padmé, Han, Leia, Luke, Order 66, Luke’s temple burning.
Vader: Bring order to the galaxy.
Quick shots demonstrating military power of the Empire, First Order, Vader, Kylo Ren, etc.
Snoke: And fulfill your destiny!
Quick shots of Anakin transforming into Vader, and Kylo/Vader parallels.
I think something like this would add depth to Kylo’s line in TLJ when he says, “I didn’t hate him” regarding why he killed his father. Twisted by Snoke’s manipulation, he believes that he must kill the ones he loves, his weaknesses, in order to be strong enough to save the galaxy from itself. And saving the galaxy would be important to Kylo because it also is to Luke and Leia, but he decides their approach is wrong. I like to imagine Snoke started brainwashing him with this stuff while he was still at Luke’s temple. He wasn’t sure if he would follow through with what Snoke was wanting him to do, but it was percolating in his mind when Luke peered into it. Luke’s reaction, then the subsequent reaction of the other students, forced him into that choice, but the end result legitimized Snoke’s propaganda and the traumatized Ben Solo had no one else to turn to. His choice had been made. Of course, I think he is just trying to justify his actions, and his motivations are likely driven by more selfish reasons, but that’s the lie he chooses to believe.
