In conclusion, this is all I deduced from such preview:
- Flame Princess is FINALLY going on an adventure.
- Flame King can contact through whatever fire in Ooo.
- Flame Princess can play card games, just like her miniature version did in All Your Fault.
- Flame Princess wears tinfoil when handling cards, and when sitting on non-fire material couchies.
- Flame King wants Flame Princess to be evil. REALLY REALLY BADLY. She is now annoyed.
- Dungeons are lumping everywhere.
- Flame Princess clearly can't look adorable and not evil in her dress and hairstyle, despite the episode summary.
- They are going on a dungeon adventure to get her mind off from the evilness.
- Finn likes holding torches.
- You do not need a torch when with Flame Princess.
- Finn has a gauntlet and his demon sword.
- This dungeon has bones and skeletons, hence the name "Vault of Bones".
- Jake is staying at home, drinking tea like a limey.
- Finn should fall into a deep hole at the beginning and the episode can be all about Flame Princess (JK).
- The episode will be more interesting than the preview, which seems interesting enough.
And now we wait...
