Heigl says that T.R. did this for her when they first met at the beginning of the series, and they went out together that very first night, so they became good friends.

T.R. Knight: I think, you know, as an actor, unless you're exceedingly lucky and you're one of the golden few, a lot of your life you're unemployed and a lot of your life you're poor. You gotta be a little insane and driven and have it be the only thing you want to do.
T.R. Knight: (on growing up gay and his coming out) You are taught you are wrong, that you are bad. [So] you don't do anything, and you wrap yourself in a little straitjacket, and you put yourself in your little room. 'Don't do it! Don't look at someone, don't touch them, don't kiss them, don't do anything!' Then maybe it's OK. I mean, sure, that plagued me all through childhood, you know, in so many ways, and that's stuff that's hard to get away from. But you have to, and eventually, you know, you do.
T.R. Knight: (on closeted actors) Everyone has their own path. You just have to respect that. I don't know what it's like to be in their shoes. I know a lot of people who make statements, but you have to do it when it's right for you. It don't think it's right to force that. It's impossible to know ... There's a lot of soul searching you have to do.
T.R. Knight: (about coming out of the closet after being called a faggot by "Grey's Anatomy" co-star Isaiah Washington) It's an awesome word, isn't it? I've never been called that to my face before, so I think that when that happened, something shifted, and it became bigger than myself. I was under no delusions, though. My friends on the set knew. We talked about it. Publicly, it's not my thing to call up People Magazine and be like, "Hey, you wanna know something about me?" I could have just let it slide and not say anything, but it became important for me to make the statement.
T.R. Knight: (about his co-star Katherine Heigl's wedding) Incredible and beautiful.
T.R. Knight: (on his short-lived romance with Meredith on "Grey's Anatomy") Shonda [Rhimes] kept the bedroom scene a secret from us until the read-through. The script just said: 'Scene to be given at read-through.' It was kind of cool, everybody read it at the same time. So it made for quite an exciting read-through. Then you see how horrible it all turned out.
T.R. Knight: (on his struggle to establish himself in New York) It's just hard with New York rent to survive, even if you're lucky to be working. The last Off-Broadway show I did was like $187 a week. Luckily, I was able to get some commercial work every once in a while that would float me.
T.R. Knight: I guess there have been a few questions about my sexuality, and I'd like to quiet any unecessary rumors that may be out there. While I prefer to keep my personal life private, I hope the fact that I'm gay isn't the most interesting part of me.
