“I’m on a diplomatic mission to Alderaan.”
“Princess, please. I literally just saw you fly away from the battle on this very ship like ten minutes ago.”"You are part of the Rebel Alliance and a traitor!"
same same.So far as we knew in ANH he had a strong suspicion. It’s a bit more of that now with the context of RO.
So? Why does he have to explain everything to his prisoner?
I think the language would have been different. I’m not sure how long the trip to Tatooine would be but I’m assuming that Vader’s navigator saw the course they took and then plotted out the habitable systems along that vector. Given how short the hyperspace transit times are, the gap between the end of RO and ANH is at best hours if not minutes.
I mean it’s either going to seem weird or not. Like in the old EU Han Solo was involved in a bid to capture the Death Star plans which means he’s already had ties with the Rebel Alliance which seems to be contraindicated by ANH. Given how he values keeping his neck safe, after already getting sucked into an adventure with the Rebels before he’d be saying no no no I’m not doing this the next time it came up. This is why I generally dislike EU-style tie-ins that try to make everything too connected. Oh, Yoda knew Chewbacca? Yeah, I know, prequel canon but it feels like EU. Either it works for you or it doesn’t.
