Having recieved an invite from Princess Twilight Sparkle, Flash Sentry says yes to visit her on what her and the ponies of Equestria call “Nightmare Night”…

“Hi Twilight! I’m here and-”
“Hm?”
“Flash? Thank Celestia you’re here! Help! Save me!”
“…And I can see you’re busy. Bye!” *Darts back through the portal*
“Um… Wasn’t he supposed to save you or something..?”
“Yeah… This did not play out the way I imagined…”

Well, he’s a highschool student, Twilight. What did you expect? He might’ve saved you from Vice-Principal Luna when you got framed for wrecking the gym, but there are some outlandish situations not even he would get involved in xD

“My ‘hero’…”
“Ehehe… Sorry I let you down, Twilight.”
“Daww, I can’t stay mad at you. I’ll let you rescue me another time.”
“And maybe next time you’ll use somepony less intimidating than me.”
