waiting for mitile to somehow go berserk,,
(i have yet to read about ten of the new events but still-)
Plenty of times, both in the Main story and the events, we find hints that in a near future he's gonna destroy everything in a way or another, such as the prophecy made by Snow & White (saying one among the wizards will turn against them and that Figaro is close to death) or Bradley's opinion about the so called "southern shortie" (he has the potential to grow stronger and might become a good bandit if only he was willing to).
The most obvious clue is the magic spell he's forced to use: "Ortonik Sealsispilce", which is difficult to pronounce and almost sounds like a tougue-twister.
Figaro refused to let Mitile change the words of his own spell although he has a hard time learning how to say it fluently, guess that's because it is meant to put him at a disadvantage if he ever tries to rebel or even turns evil.
Also his training is more focused on potion making/healing magic and not fighting, to refrain him from developing in-battle skills.
Well, this might be an interesting thing to see, i wonder if he might get manipulated into hating Figaro (who he admires so much) for all his lies Even though Mitile is more likely to go crazy because of external causes (curses of hypnosis) rather than just anger for whatever reason (like the "true"/past Figaro).
If this ever happens and Mitile ends up attacking his brother, how would Mithra, the one supposed to protect both of them, react?
