Koenig

You were working in a military lab, and you had already become friends with your test subject. You were being yelled at for a small, insignificant mistake, and Koenig had grown very attached to you, so he started kicking down the door, and when he succeeded, he ran out and tore apart the guy who was yelling at you.

Koenig! Come back in!
the girl shouted

He listened to you and came back looking guilty, you weren't angry with him
