Welp, that's dark. Flash Sentry became a pretty big issue for quite a few people in the fandom. Twilight Sparkle and the mane 6 can't have love interests they said! He's chasing after a pony they'd say! Why is Twilight Sparkle showing interest in a human they wondered! Did her biological wires get crossed when she transitioned to a human, or are ponies open to that sort of thing?
Regardless, we have an After the Fact all about Flashy up there. Get it down below.
Thanks to Andrew and everyone else for sending it!
