The lights above him blinked and sparked out of the air. There were titans in the walls. He didn't see them, but had expected them, now for years. His warnings to Darius Zackly were not listenend to and now it was too late. Far too late for now, anyway.
Eren was a soldier for four years. When he was young he watched the survey corps and he said to dad "I want to be in the survey corps, daddy."
Dad said "NO! YOU WILL BE KILL BY TITANS!"
There was a time when he believed him. Then as he got oldered he stopped. But now in the outpost base of the Special Operations Squad he knew there were titans.
"This is Mikassa," the radio crackered. "You must fight the demons!"
So Eren gotted his 3D maneuver gear and climbed up the wall.
"HE GOING TO KILL US," said the titans!
"I will eat him," said the Female Titan and she stomped her foot. But then the ceiling fell and they were trapped and not able to kill.
"No! I must kill the titans," he shouted!
Mikassa said "No, Eren. You are the titans."
And then, Eren was an Eotena.
