Kip and I were watching Revenge of the Sith the other night and she came to a startling conclusion. It is her suspicion that Palpatine is Anakin’s father.
1) Anakin was “spawned by the midichlorians”.
2) Palpatine can use the Dark Side to influence the midichlorians to “create life”.
[Update] I have corrected this theory and posted it at Pinkjoint: Anakin’s Father.
