#(osceola and lucy processing that that THING is shiro's eldest child)

[discordiansamba]

thinking about the blue exorcist changeling au, and just- everyone seeing rin's true form for the first time on that bridge on that fateful day. yukio shoots him with iron bullets, which surely would have killed an ordinary fae- but even yukio knows that his brother isn't ordinary. rin's body reacts violently, his human form dissolving and leaving behind a writhing mass of shadows, eyes and flames...

...and just as the exwires are processing the fact that that's rin, the flames blaze stronger. hotter, until they've almost completely engulfed him. it's so blinding that they have to look away- and when they look back, at first glance it seems as if rin is back to normal. he's in the form they'd thought was his true form for the longest, except-

-except shiemi can tell something is wrong.

and soon it's not just her. his chest burns, sputtering at first- and then a demon heart flares to life, blazing a bright blue. rin opens his eyes, but he's not rin- or at least, not the rin they know.

after a lifetime of being constrained, demon rin is thrilled at the chance to let his flames run absolutely wild, unbound by oberon's curse of a Name. shiemi fends him off for a short time with nee's aid, but the one who ultimately halts his rampage is a very grumpy mephisto. he spirits the now unconscious rin away, leaving the exwires with more questions than answers.

...his flames were blue.

...his flames were blue, but the fae can't be possessed by demons. so what in the world is okumura rin, actually?

(or: rin wakes up later in mephisto's bedroom with a killer headache, and fuzzy memories of the past few hours. he remembers yukio shooting him- and then things get really messy. mephisto smiles and tells him nothing, because the best way for him to discover the truth about himself is to see it with his own eyes.

...he feels different, somehow.

but in the end, though his demon heart might now be free, what oberon did to him cannot be undone- at least, not unless he takes the Name he gifted to his son back. and Oberon? oberon has no intention of doing that.)
