While promoting his new NBC comedy Welcome to the Family, Mike O'Malley (Burt Hummel) took a moment to remember Cory Monteith.

"I had many of my scenes on Glee usually with either Chris Colfer (Kurt Hummel) or Cory, and I think I had what was probably the toughest scene I've ever acted in my career as an actor opposite [Cory]," Mike (Burt Hummel) said. "I had to throw his character, Finn, out of the house because of a slur he used."

Mike wasn't just Kurt's dad, he eventually became Finn's step-father too. "It was remarkable to me, when we were shooting that scene over and over, the depth of emotion [Cory] was able to portray — the sorrow, the shame," O'Malley remembered.

"Ever since I met him — he was the fictional quarterback on that show and the very real quarterback on that set. He was an incredibly warm guy, a guy who was welcoming to everyone who came on that show from the beginning through the new folks who came on this past year. He was a very hard-working actor. I loved working with him. He was a great guy. I miss him very much."

Mike also confirmed that he'd like to return for Glee's planned tribute episode for the late actor.

"I hope to," he said. "I'm here doing Welcome to the Family, and we shoot one episode five days a week. But Burt is a very important role to me. It's been a great part and I've said to all those guys that I'll work early in the morning, late at night, Saturday, Sunday — whatever I need to do to participate and continue to be on that show honoring Cory and his passing and that character. He is my step-son on that show. I certainly plan on being there. I think they're shooting that episode when we're on hiatus."
