On the fiery surface of Mustafar, Darth Vader looks over the hellscape. The bodies of the Confederacy lay behind him throughout their bunker. It almost brought a smile to his face. They thought they were safe, but alas, they'd fallen like the scum they were.
He heard a ship's landing engines fire, and a silver glow came to his eyes. Anakin returned to the surface as a small smile appeared on his face. He'd know that ship anywhere, and he could feel her in the Force. He moved towards the platform, intending to keep her outside. He had a feeling she wouldn't approve of how he'd redecorated.
The Naboo ship landed on the platform, and Padmé readies herself for what she's about to do. She looked out the window and saw Anakin drawing closer to the starship. She moved towards the rear door, pistol concealed behind her back.
Anakin came to a stop behind the ship, ready to embrace his wife, ready to tell her his plan to save her. The door opens and before Anakin could even say a word, a blaster shot rang out. The plasma bolt struck him in the leg and he doubled over in pain, not just from the shot, but from the emotional betrayal he senses.
Obi-Wan, hearing the shot, exits his compartment and quickly grabs Padmé, trying to pull the blaster from her hands before she could fire again.
"Padmé, what are you doing?", he shouts at the senator, desperation building in his normally collected voice.
At that unfortunate moment, Vader looks up, reflections of fire in his eyes. He shouts, "YOU TURNED HER AGAINST ME!"
Padmé then dropped the pistol, and grabbed her throat, as Anakin began to rise to his full height. Kenobi, in a state of shock, could only call out, "LET HER GO ANAKIN!", but the other man disregards this. He continues closing his fist, despite Padmé's pleas, until Anakin returns, only for a moment and he sees her struggling.
He releases his grip and she drops to the landing pad, deathly still. Anakin turns away for only a moment before Vader spun back around, voice full of hate, "It's your fault, all of it- YOU MADE HER BETRAY ME!" His lightsaber sings blue and he points it towards his former Master. Obi-Wan stays completely still and replies, "You have done that yourself," never once moving for his own weapon.
Anakin, now fully embracing Vader, reaches into the Force and pulls his enemy towards him. Only then, did it dawn on Kenobi what was happening. Only then... Did he resist. Their blades locked as he landed, and the Battle of the Heroes began.
