On the final day of the traveling carnival, Big Mac decides to ask Fluttershy, however, he needs someone to give him a hand.

That's were Flash Sentry comes in.

Flash Sentry is Captain of the Ponyville Guard, personal bodyguard to Princess Twilight Sparkle, and a big brother to Scootaloo and First Base. One of these roles is harder than the others, and not even Flash's military training can help him with that.

What was supposed to be a routine night turned into a total disaster. Chimeras attacked, Flash Sentry's in the hospital, and his parents? Well...

At the behest of Princess Twilight Sparkle, Lieutenant Flash Sentry has been chosen as the captain for the ponyville royal guard. While pleased by this Revelation, he has doubts about his ability to fill the role.
Can he truly be the captain this new section of the royal guard needs?
