[[WMG: Abidani is Vizzini's distant descendant.]]
Just look at him! He's bald - check. He's evil - check. He's very confident in his wits - check. He's destined to enter battle of wits against protagonist - check. His name sounds vaguely Italian (so he can be Sicilian) - check!
I'd say, someone needs to advise Tomu to never go against Sicilian when death is on the line!
