Just read an interesting analysis on who "S" is, especially if "C" is indeed Chavo. "S" could be former Smackdown star, just traded to Raw, Steve Regal.
It makes sense - they go back to the WCW days, he traveled with the Smackdown crew with Benoit up until his recent change in roster, and he is an "S," even though he uses the name "William Regal" on tv. Also, if you think back to RAW on Monday, Regal was probably the most measured of all the guys who spoke, leading me to believe that even at that time he had an idea there was something much more morbid about this situation than was publicly let on at the time.
That makes sense to me. I’ve heard some very positive things about him. Seems like the kind of guy who tries to be a good friend. It has to be hard wondering if there was anything you could have done even when the truth is probably not.
