He managed the impossible leap to the truth by being too out of touch to consider any far more likely scenarios.
And... Uh-oh. I've just realized what I wanted to say next is better said next comic again. Um...
Hey, let's talk unaware overpowered protagonists! I made this joke while working on this comic:
"Oh no
OH NO
I MADE PRINCE ELLIOT AN UNAWARE OVERPOWERED PROTAGONIST"
Technically he's not the protagonist, but still! He actually has really good potential, and he thinks himself the worst.
There's essentially a genre of manga and anime out there in which the protagonist is the most powerful character around, but they think of themselves as a weakling. Nearly every time I've seen this, I've seen it done for laughs, and as much as I'd like to laugh along with the silly, I mostly just find it catastrophically frustrating.
"I just defeated a dragon the size of several buildings. Everyone is looking at me in amazement. There's destruction everywhere, and I'm being told again and again in no uncertain terms that no one else could have handled this monster. Oh, how they spare the feelings of this weakling before them."
And since "that's the joke," it continues like that, the character doomed to never really progress (though I'm sure exceptions exist, because that's how exceptions work, except when they don't).
(Looks at Prince Elliot) Buddy, I can't guarantee you're going to be confident before this storyline is over, but I vow I'm going to give you SOMETHING in terms of progress.
Wait, you already went from sulkily moping down the stairs to happily running off, confident in your ability to get away.
HA! YOU'VE ALREADY HAD THE MINIMUM AMOUNT OF CHARACTER DEVELOPMENT! ALL BETS ARE OFF!
