Bob Daily explained that he enjoyed working with Barrowman when he joined the show as Patrick Logan.
"He was great," Daily told Zap2It. "He was so easy to work with. He came in the first day - I think he had flown in the night before and was completely jetlagged.
"You know, he was so easy to work with and so fantastic... He did bring a very different kind of creepy energy and intensity to the show. He and Drea [De Matteo] play well off each other."
Daily also revealed that he would like De Matteo, who plays Angie, to return to the programme in the future.
"We would love that," he said. "I'm not sure where we stand at that, you know. That's kind of a business affairs question maybe, but yeah, we loved her... We would love to figure out a way to get her back some day."
