Epilogue
Four Years Earlier
The pony that presented himself as Sandy Time appeared once more, this time four years earlier than when he appeared inside Derpy's house during the whole Chrysalis, Discord, Nightmare Moon, Trixie, Gilda and Diamond Dog issue.
He missed his temporal mark by a lot, once more.
"What the hay?! Too early again! Oh how do I keep losing my TARDIS?"
He sat on the grass in the empty meadow, taking in all that just happened.
'Sandy Time?! Really, Doctor?!' he mentally slapped himself for thinking of such a stupid name. 'You couldn't have thought of something cooler?'
He checked the device, still powering up for another time-jump.
He'd have to wait a couple of minutes again.
He was surprised the vortex manipulator had worked, being powered by the makeshift magical battery he invented from the crystals the crystal ponies used. 'Wow, they really are the most powerful source of magic in Equestria, no wonder nothing happened to them last time'.
He remembered his doubts, seeing himself in the past. Luckily, him now meeting his younger self was a fixed point in time, and the fact that he did not recognize himself was only due to the fact he was too worried about the villains uniting and about how long the TARDIS was taking to return.
'Paradox averted, at least,' he sighed.
And Spitfire and Derpy… both so young. Both so whole and loving. If only he could warn them… about the dangers of King Sombra… and falling in love with a fool like him.
'Well, time's up,' he thought, as the vortex gave the signal which meant fully charged.
"Geronimo!" he said, pressing the dial, disappearing with another ZAP! sound.
