-- WWE Divas Champion AJ Lee was backstage at RAW, but obviously didn't appear on television. The Chicago crowd is known for its "smart" fans so it's likely they kept her off the show as many know she's dating CM Punk in real-life and the company was aware of the reaction she'd receive.
-- Security was on "high alert" during last night's RAW. While the #HijackRAW movement didn't affect much of the broadcast, arena staff checked people for weapons when the entered the building and looked for "offensive" signs. There are currently no reports of fans being forced to leave because of their signs.
-- As seen last night, the booking of the show was done with awareness of the vocal crowd who were not going to get CM Punk. Paul Heyman's "pipe bomb", The Usos' tag title win, Dolph Ziggler winning and Daniel Bryan standing up to The Authority and getting physical with Triple H were all WWE playing to the Chicago crowd to help the fact that Punk wasn't going to be there.
