There were lots of changes made to Monday’s WWE RAW from Atlanta and the script was re-written many times.
As of Monday morning, they were still looking to do the John Cena vs. Dean Ambrose on next week’s RAW but plans were changed and the match was moved to last night. Regarding the changes for Hell In a Cell, WWE wanted matches directly advertised, instead of ambiguous matches. Orton’s “challenge” was already written into the script before Cena vs. Ambrose was moved to last night.
There was also a segment with The Bella Twins nixed from RAW last night. This was going to lead to their Hell In a Cell match but that obviously didn’t happen.
