After defeating Proscuitto and Pesci, Bucciarati and the others head to Venice in a car. Melone from the Hitman Team finds some of Bucciarati's blood at the scene where the train had stopped and then activates Babyhead.

His button has become an eye! 
In his hand! It became an eyeball!
!أصبحَ زرُّه عيناً 
!في يده! أصبحَ مِقلة عين
Sein Knopf ist zum Auge geworden.
In seiner Hand. Zu einem neuen Auge!
– Son bouton s’est changé en œil !
– J’entends rien, Babyhead !
Il suo bottone è diventato un occhio!
Nella sua mano! È diventato un bulbo oculare!
O botão dele virou um olho!
Bem na palma da mão dele!
— Он превратил пуговицу в глаз!
