Usually when someone says "This was in the original script" it means that the current script is different. Either way it's very odd. Why would Samoa Joe be on Raw?
Fantasy booking this rumor I would think maybe he was going to come out as champion and hype up the re-branding of NXT or whatever is going on. OR this was going to be another one of those Kross situations where what happens in NXT doesn't happen in the Raw/SD universe and Joe was going to get the fuck beat out of him and lose to one of Jinder's guys clean in a minute.
