i dont think it is victor but my guessing is jack the ripper is related to Grimms. even if he is sean with Grimm spirit  or it is a specefic man who knows what is doing and as grimmval told before is enjoying killing young girls.(which i hope someone kill him in most awefull way if he is a Endezeichner grimm)

they said that wesens can see a darkness in Grimm's eye. a cat(klaustrike) can see in Darkness i think.

for hiding the grimm-hood, maybe a lense is enough. no one ever try anything exapt sunglasses!!
