With the comic's hint that Twilight's mother is the author of the Daring Do series, I suddenly wondered just how popular the books really were. I mean, the only two characters that we know enjoy them are possibly the author's daughter and one of the daughter's closest friends who had the book thrust upon her by said daughter. Heck, one could even assume that Twilight was the one to donate the copy to the hospital's book cart, which explains how she knew to rush out into the hall and grab it.
However, I think that most of us like to imagine that Daring Do is a rousingly successful book series. Regardless, I would certainly enjoy seeing some more Daring Do inspired action in the coming seasons... Surely Dash deserves a chance to plunder an ancient temple for lost secrets and live out an adventure from the books. It would be a shame to let all of that accrued knowledge of how to do proper death-defying archeology go to waste, after all.
