My first reaction: While this is not a 100% official heel turn with him attacking Darren afterward, it's pretty obvious that this is the intention this will build to, with this being the catalyst for a future solidification of his heel turn. As far as my thoughts on the issue...meh. Titus O'Neil is someone that I don't think can really go that far as a singles competitor and he's been both a heel and a babyface before with nothing being super great. Whatever.
