I wonder if there really was an "original Sherina" who died. Couldn't it be possible that Hera really reincarnated, but was only able to recover her old identity after a while and after sucking on the pacifier? In the beginning when she was tired she also blacked out for weeks only to discover later how much time she skipped. And there is the letter from her father who knew she would be able to cast magic.
