There had been much speculation regarding John Cena calling out The Rock for having notes on his wrist during a recent promo on RAW. While some had stated that Cena mentioning the notes were part of the script, those reports appear to be incorrect. It now appears that Rock had the notes as a reference point, incase he needed them during his lengthy live promo.
A source close to the situation mentions a promo from last year, when John Cena made reference of being able to the see the teleprompter The Rock was reading off of in the reflection. It is not believed that the improvised comments by Cena, which are revealing some of the tricks The Rock uses to perform his promos, is am example of the real animosity between the men.
Also, the WWE Youtube page does not have footage posted of that segment from RAW anymore. This is a surprising move, since WWE has been posting most of the Raw segments to the page, and also that the episode was promoted big time as Rock's return to the show for the first time since the build to Survivor Series. Finally, all other segments involving the two men are available on the Youtube archive.
There have been other versions of the video uploaded by people not affiliated with WWE, and have not been uploaded with the permission of WWE. There have also been other versions of the video posed by certain international television networks where it appears the notes on The Rock's wrist are blocked out via a block that is the matching color of The Rock's arm. Since WWE airs at different times and days in various markets, it would seem that the segment had been edited.
Some now feel that this is evidence of the reports that there are true dislike and competitiveness between the two.
