Allen spoke out about the prank on his appearance on "The Late Late Show with James Corden." Here’s how it went down: In Season 2, the producers gave Alfie a fake script, making him believe that after he pretends to kill Bran and Rickon Stark, the real Bran shows up and kills him instead—thus ending his tenure on the show. To anyone but Lily Allen’s brother, this might have been a devastating blow, but Alfie said, "I just took it on the chin, and kind of…you know…got on with it."
