"NOOOOOOOOOOOOOOOOOOO!" Luke shouted as he watched the shuttle explode from the viewing platform of the ship. The shuttle that was carrying Iliana to safety. The shuttle the Emperor promised he would not harm. The shuttle that just exploded.
Luke knew he vowed never to go to the dark side if Iliana was ever harmed by the Empire, but this was enough to turn him dark within seconds. He felt his heart crushing inside his body, his brain powering down, his eyes blurring as tears filled them, and then it was all gone. It was all replaced with darkness. A rushing flow of dark entered through every pore in his body like rushing river of boiling blood.
Luke stormed away from the window and through the halls of the ship, slashing things with his lightsaber, cutting down anything in his way. He threw the people he walked past against the walls, the impact denting their helmets.
"Palpatine!" He shouted, storming into the command center. As soon as Palpatine heard Luke approaching he waved his hand over Iliana's head, putting her to sleep, and, picking her up, put her in the arms of the commander who hid her behind the control panels.
"Yes, my young apprentice?" Luke came up only inches from the Emperor's face and shut off his lightsaber.
"You, you promised me she would not be harmed. You promised me she would safely arrive with the rebels and not be affected by the Empire anymore." The Emperor stepped away from Luke and towards the control panel.
"Promises can be broken Luke, when are you going to realize that?" Luke slid his lightsaber back in it's holster.
"Yet breaking the promise means me not following you," The Emperor laughed a little.
"Luke, don't you see? You are already transitioning to the dark side now, you lost the one you love most, now you are spiraling through a hopeless pit of despair." Luke scowled.
"You blew Iliana up. You can't expect me not to be mad, but just because I am mad doesn't mean I'm going dark."
"Oh Luke, can't you see? You are going dark, just as i had planned. Maybe my plan wasn't executed as i had previously expected, but I am beginning to think that this execution will be more effective." Luke looked down at the floor for a second, and when he met the Emperor's gaze again he had a new found look of hate in his eyes.
"You do not know the enemy you have just made Palpatine," he said, whipping his cloak in front of him.
"No Luke, you do not know all the allies you have just gained."
