Before the Mane 6 have a chance to seal him away once more with the Elements, Discord manages to escape at the last second.
Meanwhile in Konohagakure, Naruto is plummeting towards the bottom of a ravine and frantically attempts the summoning ritual, though instead of summoning a toad he winds up with a mouthy draconequus, much to his displeasure and Discord's joy.
Discord decides to stick around Konoha's Knucklehead Ninja and see what this new world has to offer, oh and not having to deal with those pesky Ponies is a big plus!
