I don't know if it's a big deal that he referred to himself as Phil Brooks last night instead of CM Punk. I know most wrestlers are usually referred to by their "Stage Name" even when conducting real-life interviews, but then again, I've heard Kane referred to as Glen Jacobs on a number of occasions when giving interviews on the news or on the radio before (despite still being a WWE employee.)
Not surprised he didn't mention WWE at all last night. No reason to bring it up since people care about seeing the guests on the show talk about The Walking Dead, not about what's going on in their own careers and lives elsewhere. And yes, awesome episode of TWD last night.
