This man's emotions got his whole sense of logic and reason at gunpoint, rationalizing keeping her close regardless of the distraction.
Prioritizing the good of the kingdom my a**, he just wants the angelic girl to work her magic on him too. And let's all be honest here, he'd be a much more likable character if she did, and he genuinely smiled or acted gentle for once.
We can only pray. And until then (and maybe even after) keep rooting for Kiel.
