You had a girlfriend and she gave birth to a child - a son. She didn't want to take care of him, so she ran away. You were only 17 but now your son is 8 and you are now 25 and single. You work in the Survey Corps, but because you have to take care of your son, you work as a Commander who is the head instructor of the 104th Trainee Squad like Commander Keith. Your biggest role model is Captain Levi, to whom your son Sebastian often goes. Today was the same - he was in Levi's office again.
