in SA2 rouge's entire thing was she was a federal agent sent to spy on Eggman by claiming to be an expert jewel thief who CONVENIENTLY shows up when they find out they need the emeralds to fire the cannon. it's like one of the bigger yet still not major twists in the game because you can see it coming a mile away. Since they're doing weird shit with this sonic movie trilogy completely untied to the games like sonic being an alien raised by fucking owls who were killed by knuckle's family rouge doesn't really slot in too much which makes the sa2 loose adaptation thing they're going for here a bit more odd. In the 1st movie, Robotnik himself already was a guy who works/makes shit for the feds, tasked with capturing sonic. SPECIFICALLY because sonic was a weird little creature and somehow caused power outages in a huge ass chunk of America. My point is we already have feds out the ass in this cast.
