I am. But I wouldn't be the least bit surprised if it WAS actually in a Corific and we just missed it.
Which says it all, really. :P

Desmond: Hmph! You have one measly flashback scene in one measly hidden gaiden chapter most people don't bother with and you're a woobie. I was the fucking KING OF BERN and everyone cheered when I died!
Guinevere: The entire plot of FE6 was YOUR FAULT, Father.
Walhart!Morgan: MY daddy said he was gonna put my head through a wall to help me remember. D:
Noire: I used to be my mother's target practice! D:
Zephiel: At least she wasn't INTENTIONALLY trying to knock you off! My father failed to assassinate me TWICE!
Helene: I always knew you were a failure, Desmond.
Desmond: Grr...

Misty: The sooner the better! D: I don't wanna end up married to Brock!
Brock: Hey! D:
Misty: Do you wanna end up being James and Jessie's sycophants forever in Babies Ever After territory?
Brock: ...You have a point. >|^\

And once Jessie got over her disorder, more food porn than you can shake a breadstick at.
Oh, gad. Can you imagine? THE ENTIRE FIC would be dedicated to food porn in various varieties. And the worst part is that SHE COULD ACTUALLY ARGUE IT WAS RELEVANT TO THE FIC THIS TIME.

And all crises are via external forces like Ash Ketchum or being late to a movie. And they're definitely co-dependent, even if the instability is more "we can't live without each other or nearly murdering Ash Ketchum!" and hopelessly clinging to their magic wicca and mystical psychic dreams.
YEP. D| And I knoooow. The fics become two-dimensional parodies of themselves. And considering that they were two-point-one dimensional before, that's saying something.

Oh dear. XD Well, Essie is very much against Ninian being an Action Girl. So maybe instead she could have Ninian *gasp* raise her voice!
AS SHE CRIES OUT IN ANGUISH!

And Nino cries on Jaffar about her awful family situation and how Sonia messed her up so badly she thinks she's unworthy of being loved. While Rebecca and Lowen make a huge delectable feast out of three peaches, an apple, some stale bread, one underweight pheasant and two rabbits.
To be fair, I can totally see Lowen SOMEHOW(TM) pulling that off in canon. XD Don't forget that Coriverse Lucius and Serra are bonding over orphanage!angst.

True, Jessie did have a pretty crappy childhood. But like you said, it doesn't seem to affect her in canon as much as it does in Corific. We know her mom disappeared and she likely never knew her dad. And that she was poor. And that she got screwed over by some boyfriends. But James was physically and mentally ABUSED. I get that Cori was trying to say "Jessie is not Jessiebelle because she actually likes James for who he is"-and in canon, I can sorta buy it since Jessie DOES care about James in her own fucked up way. But she still beats the crap out of him and still looks like Jessiebelle.
I was just playing devil's-advocate and pointing out that a lifetime of abandonment issues COULD screw one up, if one wanted to do some ~darker and angstier and REELISTIK~ take on Jessie's personality. But yeah, if you do that, you pretty much have to acknowledge that James would ALSO be really screwed up by a ~darker and angstier and REELISTIK~ take on emotionally distant, strict, and neglectful parents and a prepubescent psychopath for a fiancee.

I mean, canon glosses over it, but the kid ran away from home at age ten (or so) and STAYED that way, even though he's been dirt-poor, homeless, and forced (?) into a life of crime for the last several years. And that was STILL better than his home life. Fuck, but that is screwed up. That's... preeeeetty dark for a children's TV show.

Sara's mind used Protect!
Corific used FESTIVAL IN TR'S HONOR!
Sara's mind protected itself!
XD Or maybe your mind has the Wonder Guard ability? After years in wanky fandoms, it might have evolved one... :P
