This story is based off of the new Legend of Everfree Sneak Peak #3
I got the idea when Flash was talking to Twilight and seemingly pointed at Sunset and said "And we don't know each other very well."
I know he was probably just saying that to Twilight, addressing the fact that she doesn't in fact know him very well, but whatever, LOL, let's just pretend, for the sake of this story, that he was addressing Sunset.
