I take Delphine's account as true (enough) because we do know Albert subsequently refused all contact with her, and this would seem to provide something of an explanation and enough hurt and anger for why. This version of their last conversation is worse than the ordinary account of it, simply telling her she wasn't his daughter and never to bother him again.
I'm not sorry for the grown man denying reality, his own child, and not only himself as a parent to her, but even a connection to her heritage. It's cruel.
Besides — even if Delphine's recollection is a lie? Albert still behaved like a jackass for two decades. So he would have even less excuse.
I dont think there is the slightest chance of Delphine becoming a princess.....a nd I doubt if she's looking for it..
I think she's deeply hurt that he was a father to her for a time and then so brutally turned on her..
