I can’t imagine Vader saying “Liar!! You’re with him! You brought him here to kill me!”
No, he just said: “You are part of the Rebel Alliance and a traitor! Take her away!”
Prequel Anakin would have said something like “Traitor!! You’re with the Rebels! You’ve turned against us!! I will not let you get away with this!” or whatever.
He’d also pace back and forth while saying it. Then an Imperial officer would inform him that an escape pod with no lifeforms crashed on the surface of Tatooine. After realizing what planet they were orbiting, Anakin would tell his crew to initiate an orbital bombardment to kill all Sandpeople and also destroy all sand, after suspecting Leia was here as part of some nefarious sand-related plot to overthrow the Empire. He would then yell out to nobody in particular, saying “I now see through their lies! I will make them pay for their coarse, rough and irritating plotting against my Empire!!!1! It’s all Obi Wan’s fault!!”
