Flash Sentry in Three's A Crowd · 6:50am Jan 28th, 2014
Yes indeedy, Flash Sentry had a cameo in the Discord episode!
Cadance, get out of the way!
And if you don't believe that's really him and is just some other pony that looks exactly like him then see this post by Meghan McCarthy. Oh, and this reply from Jim Miller which definitely confirms it but isn't as amusing.
Sure, he may not actually be canon or anything but I hope to see more of him in the background at least. It was great to see more of him. It was equally great to see all the Flash haters crying out over his appearance. Hah.
And he's still looking as good as ever. Definitely further fuel for shipping. Yessssss.
Smile and strut, baby. Smile and strut.
P.S. Who is he smiling at anyway? Some say Twilight, some say Cadance. But if it IS at Cadance, why? Hmm. Maybe it's like 'Hey, Cadance, have fun with your sister-in-law because I'm going back to spend the day with Shining. If you know what I mean.'
