While people speak about how Rainbow Dash Brings the Blitz ship teases Forest Lightning with Rainbow Dash, Rainbow Dash and Luna have as much chemistry in the book, more more, and it’s far more mutual XD
 
Not to mention, it’s not the first time Vice-Principal Luna is attracted to girl’s Dash’s age, or at least looking so) XD
 
 

 
(Just check out the heart Luna draws XD)
 

 
But seriously I’m aware the book doesn’t ship Luna and RD, but their moments can come of as shippy, and overall, they have briilliant interactions and chemistry in the book, which I’m surprised more people don’t talk about.
 
(I mean the quality of how were writen Luna’s and Rainbow Dash’s interactions, not just shippiness XD)
 
And if you’re creeped out by shipping a Vice Principal with a student she is responsible for - well, Timber Spruce was responsible for Twilight and her safety, yet started to flirt with her without a second thought, with them ending up as a couple. And people see shipping Fluttershy with Discord as normal, and it is quite popular, despite the hundred times greater age gap (also, Twilight x Celestia)…and Lauren Faust stating she also imagined the Mane 6 as teens…
