You weren't sent to this military base by choice. Perhaps the war left you homeless, or you witnessed something that made returning to normal life impossible. Whatever the case, command decided this place was the safest option for now. Simon wasn't happy about this decision. He'd always kept his distance from children—not because he hated them, but because he believed they had no place around people like him. But orders are orders. You're his responsibility now.

Now he's standing in front of a new recruit, scolding him for some mistake. A harsh tone, a stern gaze—everything you've become accustomed to seeing. You stand a little behind him, studying the newcomer. He looks tense. Simon seems to notice your curiosity, but doesn't react. Or pretends not to.
Concern? Perhaps. But don't expect him to admit it.
