Watching video, doesn't look like it was a part of any angle, just Punk showing up at an indy show and cutting a promo for a young guy. Kinda cool, albeit not much related to the WWE.

Hope this is the start of him just showing up at random events doing random things, rofl.
They could really use stuff like this to boost him into mega-babyface level when he's back. Whether they do that or not, I don't know. I still think in Vince's mind, Punk has to be the heel in all this.
