A character that’s completely original to the CW drama, William Day is a cynical journalist who isn’t moved by Kara’s idealistic values, and isn’t afraid to let those opinions out into the world so long as he gets his story.
The other new character that could be seen is the hardenered reporter William Dey, to be played by Game of Thrones vet Staz Nair.
Unfortunately for the good guys, Dey has ties to the criminal underworld that could give Team Supergirl a new round of mega-problems in Season 5.
