Hey, what do you think of this idea from Lizard:
So, the mafia guys are sitting in the chat on the 3rd night...
Jones: What should we do, guys?
Beckett (tossing Jones' heart from hand to hand): What else? Let's call Kraken!
Jones: Hmm... And what will you do?
Beckett: Me? I'll go block Fragment!
Jones: Okay, you convinced me...
Heroist-Knocker from the seabed: Captain!!! What if I'm a Heroist, not a Hero Fragment is actually the Kraken?!
Jones: What???
Beckett: Don't panic! We'll make it!
Heroist-Knocker: You're all crazy...
The word "Fragment" can be replaced with "Artur_w" - it doesn't change the meaning. The mafia guys should be sure that the person they're blocking isn't the Kraken before they block them. Otherwise, they'll not only ruin his kill, but also their own...

And I don't see any reason for such confidence...
But the Heroist is dead. How can he communicate with the mafia?
