Anyone who has ever seen the original, or G1 My Little Pony series, particularly the original special, Escape from Midnight Castle, knows what this picture is about.
Left Side: Megan is just a little bit surprised to see Rainbow Dash. How would you react to seeing a rainbow-maned Pegasus pony in real life?
Right Side: Rainbow Dash asks, "You do know how to ride, right?"
...I hope Mrs. Faust doesn't kill me for replacing Firefly with her G4 incarnation.
