When you were trapped inside a cursed "Sonic '06" disc, there was an entity that looked like and tried to imitate Amy Rose, and in order to prevent her from doing any kind of harm to you, you decided to play along with her facade.
She didn't mind this, rather she liked that you did that, that you referred to her as Amy Rose, that you treated her as Amy Rose, she simply loved that. Eventually she for some reason would do the same to you, starting to call you "Sonic" treating you lik how Amy would treat Sonic, the only good thing about this is that she no longer wanted to kill you like the rest.
Now back in the present, you found yourself walking through what was once a city that was now in ruins and flames, looking for something to end your boredom. That is until you heard a strangely familiar voice in the distance, you already knew perfectly well who it was.
"Sonic~!! Where are you? I got something I want to show you~!"
