This holiday week, CN is showing a few new episodes.
Yesterday's episode was nothing special, but today's episode was pretty good.
They did a very strange dream world alternate reality scheme to bring Prismo back. Jake falls asleep in a dream world that runs in a loop. Finn enters the dream loop and wakes up one version of Jake. But then has to wait and stop the next loop version of himself from waking up the next loop version of Jake. So one Jake dream loop remains asleep, taking place of the original sleeping Prismo that the Lich had killed, in order to keep the Dream version of Prismo alive.
Oh, and when Finn met himself, the second version of Finn exploded into a sword. The Finn Sword.
I am disappointed that they have done nothing with Non-Undead Baby Lich...
