Meanwhile in season 3 of Gotham, things have been getting interesting. Captain Barnes gets infected with the blood of Alice Tetch. This slowly has given him super strength along with making him crazy. He kills a number of people in his attempt to save Gotham, as he thinks everyone is “guilty”, because he hears voices whispering this to him, and deserves their penance.
Also it later gets discovered that Mario Falcone, Lee’s Fiance. Has the virus. For Mario, he gets angry about the thought that Lee may still have feelings for Jim Gordon. This causes him to violently kill an number of people and hear whispers, just like Barnes. Eventually Mario comes close to killing Lee, driven to this by his madness, when Gordon kills Mario and saves the day.
