Anakin woke up to Obi-Wan's gentle shaking. Obi-Wan opened his mouth to say something, but the pilot beat him to it.
"Lord Vader. We have arrived on Mustafar."
Anakin sat up straight.
"Yes. Thank you. Don't leave without my permission. You will stay here."
"Yes, milord."
Anakin stood up first, then Obi-Wan. They both left the Imperial shuttle. Anakin was hit by a powerful invisible force when he saw the place where they landed. Right in front of the Separatists place which had been partially destroyed and abandoned after Anakin killed all of the Separatists in the place and after Anakin and Obi-Wan fought in a battle with good vs. evil three and a half years ago. And the shuttle landed right where Padme's ship did.
Anakin became irritated and paced around.
"So… what?! Is the Force just mocking me for what happened years ago and bringing me back to nostalgic places? Although, for me, it isn't nostalgic. It's traumatizing."
Obi-Wan walked out.
"Calm yourself. It could just be a mere coincidence."
"Mere coincidence, my ass." Anakin muttered. Obi-Wan held his hand to his ear.
"Did you say something?"
"Nothing. It's nothing."
"Right. Nothing. What am I thinking?"
"I don't know. The Force doesn't allow me to read minds."
"I know. I was just talking to myself."
"Oh, dear Force! Obi-Wan, are you feeling alright?"
"I know you're irritated, Anakin, but there's no reason to be testy."
Anakin playfully scoffed. Obi-Wan actually cracked a smile. For a moment, it seemed like things were normal. Like Anakin and Obi-Wan were back at the temple. But Anakin was brought into harsh reality when he remembered that he had a job to do. He stared intensely at the things in front of him. He stood, prepared to do something serious, for a while, but then he loosened up and asked Obi-Wan,
"What am I supposed to do again?" Obi-Wan sighed.
"You're supposed to rid the Dark Side from yourself."
"And how in the Force am I supposed to do that?"
"...I don't know." There was an awkward silence.
"Then why are you here if you don't know how to 'vanquish Darth Vader from myself?!'"
"I don't know! But I decided to come because this is where you and I fought."
"Oh! You decided to come because you felt some kind of 'nostalgic' feeling in this place?"
"...I don't know."
"Don't, 'I don't know.' me!"
"I'm sorry!" Anakin facepalmed.
"Oh Force. We look like two idiots just standing here."
"Yoda didn't tell me anything."
"Oh, that's a surprise. Did he really not tell you anything or did you just not understand because he's always talking in riddles? 'Young Skywalker, go to Mustafar you must.'" Vader attempted to imitate Yoda's voice, but failed horribly.
"He didn't tell me anything. And yes, although I do agree he talks in a rather unusual way, I don't think we should talk about Master Yoda in that way."
"Right. Right. So what are we supposed to do now? Do we go back to Tatooine and demand an answer from Yoda or do we just stand around here, looking like idiots, until something happens?"
Obi-Wan seemed to be thinking deeply.
"I think I have something."
"What is it?"
"We can fight. Like we did before."
"Wow. You really are insane. I don't want to fight you! I might actually win this time!"
"So? You won't kill me, right?"
"Accidents are out of my control."
"'Accidents.' Right."
"I will try to not let anything happen to you, Master, but I can't promise anything."
"Fine. Let's do it already and be done with it." He ignited his lightsaber. Anakin pointed to it.
"Give me your lightsaber then."
"What? Why?"
"I don't want the red one that I have."
"So?"
"So… Give me your lightsaber. I want a blue one. Just like the one on Mustafar. Hey, it was your idea."
"I'm not giving you my lightsaber. A lightsaber is-"
"-a Jedi's life. I know. I know. You told me a million times. And yet we always end up having to get a new one. Just give me your lightsaber."
Obi-Wan sighed and Anakin thought he was actually going to give him his blue lightsaber. But instead, Obi-Wan took out a familiar looking one out of his robe and threw it at Anakin, who caught it. Anakin recognised it. It was his. Obi-Wan must've taken it before he was planted into the black suit.
"Why do you have this?" Anakin shook his head. "Nevermind that. Let's duel already. The heat and the temperature of this planet are inconveniencing me." With that, Anakin ignited his old lightsaber.
"And Obi-Wan?"
"Hm?"
"Even if I lose again a second time, I will still consider you my Master." Obi-Wan smiled.
"Thank you."
