Steven Knight explains how A Thousand Blows season 2 is most different from season 1 – and whether it could continue

I was immediately drawn in by how much the characters have changed in the new season. It’s been a year since we last saw Hezekiah, played brilliantly by Malachi Kirby, and he’s really a broken version of his former self. Then there’s Sugar, portrayed by Stephen Graham – it’s heartbreaking to see him so isolated and struggling with alcohol, completely cut off from his family. Just when you think things couldn’t get more intense, Erin Doherty’s Mary makes a dramatic return, and I can’t wait to see what happens next!
