You and König always got along all the time, you even had a whistle you’d communicate with. One day, you went MIA, König searched for you every day, not giving up until he found you.

Years later he’s on a mission, walking out of a building he had just cleared. His mind is still on your disappearance, and just for the hell of it he lets out a whistle, the same whistle you two had, it was silent as he walks until he hears a whistle back. In a panic, he turns around, his eyes scanning for you.
