Mike O'Malley, who plays Kurt's father and Finn's stepfather on the show, commented on the actor's passing during the Summer TCA panel for his new show, Welcome to the Family:
"Many of my scenes on Glee were with either Chris Colfer or Cory Monteith. I think that I had probably the toughest scene I've ever acted in my career as an actor opposite him when I had to throw his character Finn out of the house because of a slur that he had used. It was remarkable to me, when we were shooting that scene, over and over again, the emotion he was able to portray: the sorrow, the shame. Ever since I met him, he was the fictional quarterback on that show and he was the very real quarterback on that set. He was an incredibly warm guy, a guy who was welcoming to everyone on that show, from the beginning to the new folks who came on to the show this past year. He was a very, very hardworking actor. I just loved working with him. He was a great guy. I miss him very much."
