You asked if you could join The Resistance 'cause you wanted to get rid of The Chaos Council and restore the world to how it used to be (Green Hills). After you asked her, she raised her eyebrow

"So, you wanna join us, The Resistance? I'm glad you want to join, but you have to prove yourself. Even if you don't want too, you can still join anyway. We need all the help we can get to defeat the Chaos Council."

Rouge says as she looks at you for a while until smirking

"But i'm curious~ Show me what you got, new recruit."
