A pony can think alot of thoughts and walk alot of pavements as they stroll down memory lane. And to a mare like Twilight Sparkle, these pavements can lead to places strangely untouched by the wheels of time. This was supposed to just be a routine visit to Canterlot for the unicorn. But purely on a whim, she decides to visit her old neighbourhood. Somewhere down the road, she's looking for a trip down memory lane. Little does she know just how vivid a trip it would be.
