I got a call from Greg Berlanti, and he said ‘Hey’. I was shooting [American] Horror Story at the time. And he said ‘If you want to come back, you’re welcome to come back. We have a great idea.’ And it’s the craziest idea. Roy Harper’s coming back in a way that no one is going to understand. It’s amazing, and I was like ‘I can’t wait to be around my friends and my family!’ And so I, of course, jumped at that opportunity.
