The news about Edge’s return on the March 9th episode was not a secret because he was being locally advertised by the Capital One Arena in Washington, DC. The local ads and a tweet sent out by the arena were deleted over the last several days.
Edge will be on the show to address Randy Orton and presumably set up a WrestleMania match. The last time he was seen on WWE television was on the Raw after the Royal Rumble when he was brutally attacked by Orton.
Next Monday’s Raw will include the aftermath of the Elimination Chamber and WWE will begin putting all of their focus towards hyping WrestleMania 36.
