Mafia 33. The American Dream

In any case, the whistler didn't have a prosecutor, which means Vishmaster is still Mafia.

Considering the ambiguous descriptions of Lizard and the hidden features, most of which we still don't know, I wouldn't be so categorical. Perhaps the cough is just an attempt at a Mafia block, to which I have immunity, and I'm not even aware of it.
By the way, if they really used the serum on Plesena-Naji, it becomes quite logical why the Mafia eliminated him so easily.
