What if Steven Moffat wrote an episode of MLP? This, probably.
I blame Tumblr for this comic.
Also, I was surprised to find that no one had made a Steven Moffat pony OC! C'mon fandom! Get your act together! I thought you guys were supposed to have ponified everything by now...
OCs featured: Meghan McCarthy, Jayson Thiessen, Sibsy, Amy Keating Rogers, and Steven Moffat.
