Well, as long as I seem to be among a minority in regards to getting this moving again...
K and Alice remained together, eventually getting married and living happy lives together. The baby Missingno. K took in turned out to be instrumental in solving the issues everyone was having with ??? Island- once the Missingno. all realized that the abandoned infant Missingno. had been taken in and lovingly raised by a human, they began to reconsider their previous views about humans. Especially once K revealed that he was raised by 3TrainerPoke and could understand the languages of all Glitch Pokemon. K was also able to clear Alice's name by convincing everyone that Jerem was at fault. K made sure he and Alice were present at Jerem's execution. With Jerem gone, the other corrupt island leaders lost heart and were overthrown with relative ease. There were still minor squabbles, of course, but for the most part, peace reigned supreme throughout the islands.
Seph got tired of this place and said to Amaterasu: "You know, this is boring. Let's go Amy." Amaterasu: "mhmm."
So Seph and Amaterasu returned to the boat they came with, went back to Fire Isand and took over everything. They now live in a giant castle full of luxury and protected by Arcanine, Houndoom and Magmortar guards with a Darmanitan as captain. A Chandelure is their personal butler and a Rapidash Seph's personal mighty steed. All hail the mighty Fire Kaiser! \o/
