Gilda wants to be friends with RD again. Last time she was in town she sort of... made every one of Dash's friends her enemy, but especially Fluttershy. She will do anything that she can to get her best friend back. Even... apologize.
It is told from the perspective of Tank, who is simply sitting in Rainbow Dash's home, and each day Gilda speaks with him about what happened, because who else is she going to tell?
