omg u feel that way too? me too! i mean the motive is pretty obvious, all of the victims almost have similar qualities with ryan (is that his name? (≧∀≦)) and when you look at the time line, the killings have happened almost days near after the confession. using that duke's own words, he was overjoyed when his confession wasn't rejected right away. meaning he thinks there's a chance and as we can see with this recent interaction, he is clearly obsessed with our
ryan, he probably got impatient and used the victims as replacement/substitute for ryan for simulations of his dark fantasies. the expensive ribbon used to tie up the victims and the carriages' connection to the duke would also make sense because in that era, who can afford that shit? definitely not the guy they caught. my theory is, this guy they caught, he's the one finding the victims, drugging them and helping the duke take them. he prolly got curious (maybe he watched while the duke was torturing the victims or accidentally saw it) got sexually riled up and wanted to try the same thing so he chose a victim of his own to try the same thing. although i could be like, totally wrong, the way things are progressing, i can't help but think this way xD
That damn man who grabbed his shoulder is the damn killer, fck him (︶︿︶)＝凸
