Piranha battle

Not exactly branches to any unused amazing events of anything like that, but for instance there's one where if you lose the battle at Narshe it shows Kefka and the soldiers all walking up to the frozen esper. That event is good to go, NPCs included and everything, but it is never used.

Besides that one though, there's just a lot of possible branches to dummied out dialog that can be found in the event code like:

This line is never used, seems to be like he was possibly thought at first to be going to Thamasa, or something:

CB/CBC7: 4B Display dialogue message $0286, wait for button press
TERRA: …
Where's GAU…?
LOCKE: He hates ships.

Here Shadow has dialog for the WoB airship but that can normally not happen:

CB/430C: 4B Display dialogue message $067D, wait for button press
SHADOW: ……
Why am I here…?
For the money, I guess.
CB/430F: B2 Call subroutine $CAF59D
CB/4313: FE Return
