Okay i stopped around the before going psynching with boss
here's my theory so far:
in mizuki's route so said something peculiar "ironic, killed by your own father" date is so's son. His memories are somehow erased by So covering for his son being a murderer and probably the original cyclops killer.
the crime was then pinned to falco, who killed a lot, as an assassin but wasn't the cyclops killer
the explosion was probably caused by the psynch machine in the factory, probably that was used to erase So's son memories.
I am still not clear on several aspects but the story has cleared up quite a bit.
why was shoko killed, why iris's somnium in the polar bear timeline has the original cyclops killer scenes, the new cyclops killer (assuming it isn't so which i think it isn't, at least not shoko's)
who is boss too ( which i guess i will learn tomorrow)
