Executor Meditation Pod: Vader knew that in that one moment he would do anything for his son and he decided that no matter the cost,even death itself would be worth it,he would save his son. Vader knew that for once his anger would not serve either him or his son well and he concentrated solely on his mission of rescuing Luke and realized that he would need to concentrate all his power into making himself invisible to the Rebels. He knew that the only way he would be able to save his son would be if was able to trick the emperor into letting him leave the ship and the only way to do that was to convince Palpatine that he was building on his powers and building his anger. So Vader requested an audience with the Emperor through a hologram and then he opened all the old wounds that had haunted him for 20 years. He asked that he could be allowed to visit to Mustafar to soak in all the anger,pain,and indignation he felt when he burned in the lava. Vader saw that the Emperor had an almost giddy look in his face at the prospect of his pain and growth in the Dark Side. "You may go my friend, but when you return I expect your power to be tenfold. Vader took this as a dismissal and left. Palpatine remained on the screen and left behind these ominous words,"the plan is in motion,prepare for phase 2"
Vader ran past the main bridge on his way to his ship in a blur of black fury,so fast that a newly recruited officer knocked into the Dark Lord. This trembling young man was the perfect target for all of Vader's feelings of helplessness. And he crushed the young man's neck in a steel grip before continuing towards the hangar bay,leaving behind another mess to clean up. As he was running Vader used the force to start the ship and R-2 unit. When Vader entered the ship the R-2 announced that "all units are functioning and ready" and Vader was off in a blur of light towards Naboo. Inside the ship in the presence of the stars he promised Padme that he would save their son.
The Forests Of Naboo-Using his force abilities and the strength of a father needing to protect his son Vader sped past all the Rebels without even getting a glance. He was within 100 yards of Luke's force signature when he was stopped by a gun to his chest. Princess Leias standing in front of him with the most menacing and defensive look that he has ever seen "I swear if you take one more step towards Luke I will kill you in the most painful way possible" said Leia. " Your Highness" was Vader's only response. This seemed to only irritate her more but she maintained her composure and responded " Don't you play the Dark Lord car on me I know you aren't here to kill us, you are here to rescue Luke". "And how do you not that wondering about both this assumption and her ability to see him" Questioned Vader. "I can feel his pain and I can see what you are thinking,I don't know how but I know what your intentions are." "Promise me you'll take him, promise you will keep him safe" she continued. "What" was the only word that could come out of his stunned mouth. "Anything even working for the empire's better than this torture." Said a somber Leia. So Vader trekked into Luke's Cell with his daughters approval,even if he didn't know the truth yet.
What he saw inside horrified even him.
