After the peril that came with oxygen deprivation, courtesy of the vacuum of space, The Doctor was left temporarily blind, though it wasn’t enough to prevent him from leading the charge to save the space miners that were being zombified to preserve oxygen.
And just as we thought that everything was ok, with The Doctor rocking the sonic shades again, we learned something quite disturbing: Twelve’s eyesight didn’t actually come back as we’d previously presumed, and he’s still very much blind.
While this week’s installment of Doctor Who, “Oxygen,” attempted to deliver thrills and chills in space, perhaps the biggest bombshell came once the Doctor, Bill, and Nardole returned home following their adventure.
