So, after we lost Grandpa we (eventually) piece together how to use the "Battle Gimmick" he gave us. The game also does some brilliant misdirection in this episode. In spoilers:

• Previously, bosses (or what I thought was a boss) like Bosho-Clove were CLEARLY foreshadowed because you saw the sprite in the "overworld" first. This time, the boss we encountered was treated as a random encounter, but it had a little "cutscene" beforehand and a different (rad) music track. I wouldn't say that boss-as-random-encounter is a "first" because there were some bosses and optional bosses in Final Fantasy 1 that were random encounter. What IS kinda new is the misdirection where you expect all boss fights to be a certain way, and the game really pulled the carpet out from under my feet.

Anyways, this game is great. By far the most exciting part yet.
