Casey will want, very badly, to remain his old reticent self. He recognizes, however, that things haven’t been working. And so he proposes a bargain. He offers to tell Marie everything, but with two caveats. First, “Everything” covers only what he remembers that is relevant to his relationship with her (not in that sense, you know what I mean), which may not be much. And second, for that information, Marie has to help him get all of his memories back, as well as properly sorted out. And the deal doesn’t include anything he re-learns in that way, though he might (MIGHT) be willing to part with slightly more.
His revelation won’t be everything (duh), but it will hit a few crucial points, including the fact that Casey has been around, in some form or other, for a LONG time, mostly because of supernatural reincarnation abilities that will probably never be fully, or at all, explained. Based on what he can remember, he THINKS that he probably made contact with Marie after the fire, based mainly on her hallucination and the fact that it seems to be the sort of thing he would do. He thinks also that he was lying to her for a long time, though he doesn’t now remember for sure, nor does he remember anything about what he was lying about. I mean, yeah, the whole supernatural reincarnation thing, but there was more to it than that.
In other words, revelations that mostly open up a huge can of worms, and a pact, such as it is, to find out more, with a tacit understanding that when and if they succeed, Casey won’t reveal anything else.Casey hasn't admitted to extreme age, but he has admitted to not knowing his age, and since he seemed to be a full-grown man rather than a fifteen-year-old boy in Marie's hallucination, there may be some implications of agelessness there. He has also more or less admitted that he may have been lying to Marie, though accidentally, since he doesn't remember her from ten years ago. He and Marie haven't made a deal to get his memories back, but they seem to be having a conversation in which they try to puzzle out what's going on, and that's really a first for Casey. So though Erwaro's answer isn't exactly correct, it's close enough for jazz. Erwaro has thus earned three points.
Of course, being Casey, he will not reveal all of this. He will only admit to having made a deal with the Devil a long time ago and having memory problems.I agree with Tuxgeo that this is an excellent theory. It may or may not be true, but it's very clever.
Casey will reveal something – but it will be mostly lies.
Sometime these days, he will say to Marie: “No, I am your father.” Which
would be possible, as he has been around for a LONG time. And of course
Marie’s parents aren’t her real parents – in a story, they never are,
even your aunt and uncle aren’t really your aunt and uncle (only if it’s
your second and third cousin, once removed, then it might be true and
you weren’t exchanged by elves after all).
BUT: Casey is lying, as usually. Marie’s real father is a backward aging pirate living in another universe, which can be reached through a vortex in the couch in the basement (which is why Marie is so attached to that place).
And: Marie’s memories are wrong, that’s why she has so much trouble with them. When crawling through that “tunnel” in the burning house, the real Marie Dumont went through a portal to fairy-tale world, where she now works for Frau Holle as Pechmarie (having grown up in the 20th/21st century, she doesn’t know how to deal with a fairy-tale household). The Marie we know came through the other way, escaping thraldom in Frau Holle’s household. To cover this up, Marie’s memories have been tampered with, resulting in her annual crisis when the real memories try to break through. Even when deciding to confront her memories, Marie couldn’t go further back than the tunnel – for obvious reasons. Casey is, of course, also from fairy-tale world and followed Marie – only time will tell whether he means well or not, but given that he is the fairy-tale devil the probability lies strongly on one side. Quite a number of other WoB characters come also from fairy-tale world, through different portals and with different amount of memories. Barbara, for example, knows that Casey is the devil.She had me at "exchanged by elves." Nobilis knows my love of fairy tales well.
I’ll go with my previous theory. Casey’s going to reveal that Marie has been Satan the whole time, but she had traded places with Casey way back in the day. Casey tracked her down and decided to try and trick her at the hospital by pretending that he wanted to trade places with her (possibly actually switching bodies) for a while rather than a regular deal. In fact, once they traded places, she’d be stuck forever since it would really be a switch back.
Then again, the rumors could be true and Casey could really be a Time
Lord stuck in some alien child’s fairy tale construction. (This isn’t a
serious guess. It would just be awesome.)
