I have only watched the anime, but I'll drop my theory anyway:

Emillia and Subaru become lovers, but due to their different life spans Subaru inevitably dies first, leaving her in despair. By some means, she goes back in time to be ruinited with him. Perhaps much further back as a means to amass the power needed to guide Subaru down the path to immortality, by preventing him from ever dying, and perhaps helping him to gain power of his own. Obviously a lot of paradoxes would be involved, but if Satella = Emillia turns out to be true, then paradoxes are unavoidable anyway.
