Noiz’s eavesdropping isn’t great, but what this scene does right here is REALLY interesting. You can bet that this information about Mink (INCLUDING HIS BIRTHDAY AND BLOOD TYPE) is not common knowledge. That would be something from prison records. Information about his handedness? Only obtainable from surveillance. When Noiz divulges that he has possession of this information in such an obvious and public way, it’s a warning: ‘if you think that this is all the dirt I have on you, think again.’
Noiz effectively demonstrated his skill at information gathering while simultaneously taking the piss out of Mink.
And Mink? He’s found himself another tool to use in his quest for revenge. If he understands Noiz’s display of power, he doesn’t care. He’s interested only in how he can use Noiz’s skills for his own ends.
I’m really impressed with how this ‘additional content’ from the anime seems carefully considered to fit in with existing characterization.
Now let’s talk about MiNoi having really aggressive and insane sex.
