This episode was pretty good. I can relate to having people overstay their welcome.
Man, how long has Gunter been rebuilding the Ice Kingdom? It seems like Ice King's been living with F and J for weeks.
Ice King, why'd you have to summon a demon? Somebody call a space marine; they're excellent demon killers.
Welp, there goes Finn's demon blood sword. This guy keeps on losing his swords. What will his next sword be? Probably one forged by aliens using mystical meteorite metal.
Oh crap, the demon's got Jake! And the episode ends on a cliffhanger! Whyyy?! I don't wanna wait another two weeks to see what happens next. I bet Finn is gonna go into the Nightosphere and get his Doom on.
