And of course Matthew Glave who’s going to come in and play Oscar; he’s been around since Season 2. He’ll charm you. He will entertain you. He seems so funny and harmless

Matthew Glave will also return as Oscar Hutchinson, Fillion confirmed. “We’ve known [him] since season 2,” he said, noting Oscar “seems affable and charming and hilarious [but] don’t turn your back on him. He will literally stab it.”

Fillion called his role as police officer John Nolan "probably the best job I've ever had" in a Tuesday morning interview with "Good Morning America." "God, I'm having a lot of fun. I'll tell you, 31 years in the business, this is probably the best job I've ever had," he said, speaking with "GMA" co-anchor Lara Spencer.
