Haven't seen any post yet and I only just now finished watching the two episodes. Watch out for spoilers if you haven't seen them yet!
It is quite a different tone than Adventure Time still, like the intro music is more spooky/weird than the happy tune in AT.
Also wondering if more from the Distant Lands series pops up, like the dome world in space from the BMO episode.
Love me some new Prismo though, too bad he has not been having a good time recently.
desertion can also mean something like leaving a gang or army or similar without cause, like going AWOL.
That one is a fun one to theorycraft, like a plea deal to leave the citadel was to work for these people and he did a runner.
