Balthier will go along to the desalination plant. He will be one of the ones kidnapped. However, this isn't his first time imprisoned in a strange magical dungeon, so he'll decently keep his wits about him and escape enough to meet up with rescue crew or help others. However, the torture definitely gets to him (esp the emotional) and is going to break what calm he'd mustered since arriving.

EDIT: if we don't have many people getting kidnapped, I will push him more this way and let him be helpless sooner. He's used to saving people, so having to rely on others or getting turned around after escaping are appealing b/c they are upsetting.

EDIT EDIT: I think I misread what we needed BUT skills for rescue and kidnapping times: Can swim, has a gun, has escaped dungeons before so knows how to sneak and use maps and such. If magic is back, he has white magic and stealth magic, and has Echoes which are large scale attack magic.
