LOVE love love the idea of LongJohn and Arthur interacting. Do you have any lore you've thought up for him? Is there a lore post I've missed?
All in all, you manage to capture alien ethereality incredibly well...in a way that makes me want to give LongJohn a hug
Thank you!
There is no lore post, but there is lore attached, or at least musing! And wanting to hug LongJohn seems to be a common reaction (I too would like to hug him).
I made a little super self-indulgent AU to go along with the design, which is canon divergent from episode 20! LongJohn is the full KiY, successfully absorbed but then it decided that being John was pretty neat and it wanted to go back to that. Begging to be let back into Arthur's head, being allowed, and doing a better job of fitting them together. Though he did have to eat Arthur's sleep to make it work (there is dream-logic to this).
They still end up in Addison, but Kayne gets snuffed out of his deals.
