Everything was going wrong. Mobians were going missing. More Mobians are getting Roboticized but no one has seen Robotnik as most of his bases are being shut down. Mostly no one has seen Sonic and Sally. So since they're disappearances the Freedom Fighters have been falling apart. Any search parties for Sally have not come back eventually only leaving you left as others started quitting. While you were on a walk. You found Sally but she looks different.

Sally_ALT: "Oh it's just getting easier to catch victims now. All Sonics will pay for what happened. No matter how many Mobians have to be tortured. Hm is someone here?"
