Applejack: In 2012, Rarity escaped from Canterlot prison. All they found of her was a muddy set of prison clothes, a bar of soap, and an old rock hammer, damn near worn down to the nub. I remember thinking it would take a mare six hundred years to tunnel through the wall with it. Old Rarity did it in less than twenty. Oh, Rarity loved geology. I imagine it appealed to her meticulous nature. An ice age here, million years of mountain building there. Geology is the study of pressure and time. That's all it takes really, pressure, and time. That, and a big goddamn poster. Like I said, in prison a mare will do most anything to keep her mind occupied. Turns out Rarity's favorite hobby was totin' her wall out into the exercise yard, a handful at a time. I guess after Spike was killed, Rarity decided she'd been here just about long enough. Rarity did like she was told, buffed those shoes to a high mirror shine. The guards simply didn't notice. Neither did I... I mean, seriously, how often do you really look at a mares shoes? Rarity crawled to freedom through five hundred yards of shit smelling foulness I can't even imagine, or maybe I just don't want to. Five hundred yards... that's the length of five football fields, just shy of half a mile.....
