I realized why Grimmer is so off-putting to me even though he's seemingly been doing nothing but good since his introduction. Every time he interacts with someone, he's always wearing a smile. When he's alone he can actually show other emotions, but when interacting with people it's just that damn smile. His spy training is just shown so readily through it and the more you see him the less you trust him cause it just seems so fake. Which is why when he doesn't smile you get the feeling of hjs real emotions. And all this became so obvious in just 3 chapters, jeez Louise. Hats off to urasawa, great freaking story telling.
