“I can’t say too much, but it also causes tension between Teddy and Owen,” he added. “Because there have been decisions made, but I think they’re going to fight to get there. But it’s a little difficult for a while.”

The Scottish actor also opened up about his future on the show after being a part of the ABC medical drama since 2008. He said: “I don’t know the answer to that question. I love playing this role.”

“Meg Marinis, our showrunner, is writing the role and all of our roles,” he added. “I feel like she’s refreshed all of us as characters. She’s given us new things to work on and work through as characters. As long as that continues, I’m happy.”
