Adel was a wasted opportunity of a character (Eh, may have spoilers)

[Kawaii Ryûkishi]

An interesting point I found on the FFWiki, though, is the text at Timber TV Station: the "noise" broadcast over all the frequencies is in fact lettering that spells "I WILL NEVER LET YOU FORGET ABOUT ME", "I AM ALIVE" and "BRING ME BACK THERE", theorised to be the thoughts of Adel confined in space... probably the only other direct communication she's ever shown to have with the player.

I AM ALIVE HERE

BRING ME BACK THERE

I WILL NEVER LET YOU FORGET ABOUT ME


Definitely the creepiest words ever conveyed in an RPG. They alone justify Adel's role in the story, and the game certainly couldn't have been hurt by more content along the same lines.
