Missions and Bearer responsibilities can mean spending a lot of time away from loved ones, and that's one of the reasons Rainbow has brought Tank (the most awesome pet ever!) along with her to the Trottingham fair. Sure, she'll be stuck at the Meet A Wonderbolt booth for the whole weekend while the rest of the team actually does stuff, but at least she'll have company. And since being at the booth gives her the chance to sleep in, Tank can just use his rotor to go out and grab her some breakfast. Besides, even if something happens to go wrong along the way like, say, having the rotor leaking glow, it'll all work out. Ponyville's perfectly used to this sort of thing.
This isn't Ponyville.
And Trottingham's residents can be a little... off.
