We learn that Snoke took twisted to a new level in this green planet, saying he chooses to live there (more like hiding), because it was a place made to hold back the dark. Now, it still has its overgrown plants that weave themselves through bones and skulls of multiple bodies. And Snoke comtrols the plants to crush the bones. Wow, you just keep getting worse Snoke. There's a slight Hux cameo, with just his voice placing a call in to Snoke. Who brushes it off and does not tell Ben who he is (or who he is to him. For all we know this is an act-which of course it is).
We see Ben thinking back on memories of when he was a young boy with his uncle facing off against the knights of Ren, and how they saw the shadow in him (the dark). There's also a memory of Snoke speaking to him in his head at that young age and calling him friend.
Anyway, we also see how Ben wanted to pilot the ship on this trip with his uncle. This is referencing Ben Solo's true dream in the series. He wanted to be a pilot just like his father, who was his hero. But as older Ben say's, the name Solo is a lie. Ben feels betrayed by his father who always left him behind on his own, lied to him, sent him away and then never came for him.
Favorite quote:
That's exactly it, Snoke. Obi-wan Kenobi... Big famous jedi. Everyone thinks I'm supposed to be him. I never even met him.
But.. one more thing. You said you could sense the shadow in all of us-- That's right. We've all got it. But you know your apprentice does too, right? Powerful. Can feel it. Better be careful., jedi man.
