Kratcy gets infected then Yoshka after a while lol
Also Kratcy and Yoshka are russian
also The Darkness/Corruption amplifies characters' power
also if the character you play as is overprotective for another character, being infected means the overprotectiveness gets amplified into a mindless, uncontrollable obsessive devotion to assimilate that character to never leave you
and that amplification in Kratcy's overprotectiveness happened to him
any infected has pure white eyes and a grin or a smile
