Wait... first he bashes Brock for his antics and now he's all concerned and says people shouldn't do the exact same thing he did less than a month ago? So it was just for the show? So he's basically no better than Brock? Yay! Glad we found that out before the fight.
Don't get me wrong, it's a nice thing to say, but this is a case of "Do as I say, not as I do" and I don't really know what to think about Carwin.
