Mafia 47. Battle of Movie Heroes

Arandor had Potter, and then a whole bunch of other people.
Sivvi was blocked.
The winner was checked by Holmes, Toxa - by Poirot.
The Policeman was protected by the Terminator.
Toria was killed by a maniac. I'd guess that Toria is the Joker.

As for the note from Saw, I remember that the Policeman in Toxa's mafia liked to change the names of the characters, but he mostly writes correctly, while our acquaintance doesn't put spaces after half of the punctuation marks, just like Jack.

Ple-Sen said something else about a cartoon with that title or something, I don't remember.

Yes, I remember that too, but I didn't watch the cartoon, I read the story, so I'll look it up now, I don't want to search the whole topic to find profiles.
