Just a short drabble set after the season five finale and the effect it had on Anakin.
"I'm not coming back."
Four words. That,s all it was but to him, it was everything and yet still nothing. The most important decisions someone could ever make. To walk away from everything that they knew and how they had been brought up. To him it was everything when she left because she took his all and kept it as she slowly walked into the sunset. It was everything because she was his friend, she was like a sister to him. He had no family but she was as close to one as he could get.
It was nothing because without her everything was meaningless. Get up, wash. Do a mission. Just go through the days with no life in it. She took that when she left. Lifeless and dead inside. Haunted eyes filled with the broken trust of Barriss and the council. That's what he saw in her when she left and now it haunted him.
She had left him a husk. The missions no longer full of the thrill the dynamic duo had felt saw through them as they were one with the force. Now he was robotic, doing everything precisely no longer breaking the rules for the good of the people. always doing what had was needed not what was best.
Everything was lost in those four words and it just tilted the scales just a touch more to falling into the depth of the darkside.
