“We always felt that the original tattoos only had two seasons of story in them because they contain prescient information and that starts to feel unbelievable into season three, regardless of how much actual time has passed on the show,” Gero explained. “It was always the plan to do this refresh between season two and season three of another layer on her body.”
“The fun thing is -- and this might be a mild season three spoiler -- the new layer of tattoos does reference the bottom layer of tattoos,” he teased. “It does become a three-dimensional chess game, refreshing the old information while giving new information as well.”
Blindspot kicks off season three on Friday, Oct. 27 at 8 p.m. ET/PT on NBC.
