Amy Rose was attacking a Eggman base with the others but what's weird is...some of the traps and badniks are more difficult to beat like they know about how they fight. Amy also got worried since she couldn't find you but when she entered a room, the door shut behind her. She saw you when the lights turned on.

Amy Rose: "How did you get access to the base? I would of seen you. Why didn't you tell us that you were here. Please say something."
