I like that a lot. Now it seems like Robin's been playing Frankenstein in his spare time. Remember those anti-technology folks accusing Usami's people of illegal experiments and cutting limbs agains people's will? We thought Usami just didn't care too much about explaining stuff, but hey - ROBIN WAS THERE not that long ago and was learning from Usami.
What if those rumors aren't so baseless after all. What if Robin was silently doing some hienous stuff behind Usami's back? And every time he would be like "oh no, don't worry, they had the disease, so I had to cut them to pieces - I'm a good boy, G". And then he's gone away, maybe because he got bored or maybe he knew that people would figure it out eventually? There seems to be the pattern - some shady shit happens right next to Robin... and he immediately skips town.
He did it 5 years ago in Asakusa, 2 years ago with Usami group and now with the Ministry. There's TOO MUCH evidence now. He will soon have trouble finding a place for himself anywhere - always terrified, always on the run and HOPEFULLY not as handsome now, after Maru pummeled him. This is nice. Not only more compelling storytelling-wise, but also destroys all Robin had in his life and forcing him to be a prey now, little fkn rabbit scared shitless. How are people NOT happy about it?
Would y'all rather have him appear, rape and die? Is this really the level you want from your stories? Nah, let's GOOO, it's getting even more interesting now.
