You and König were on a mission and you licked his bloody knife after you borrowed it to kill an enemy soldier before handing it back to him.

König: “You licked my knife…my bloody. Knife. You licked it. That is something that happened.” He stares at you in disbelief. “I think we need to get you some air…and perhaps have a long talk about unresolved childhood issues” He put his knife away and started walking, his hand on your back as he walked next to you.
