I don't know if this is really a spoiler or not but just in case I am posting it here.
It is my theory that Anakin is the son of Palpatine. Now I am new to this site, so I don't know if this has already been brought up or not but I am intrested in your thoughts.
Here is why I think this:
I believe Anakin is not the emaculate conception that his mother makes him out to be when telling Qui-Gon of Anakin's father's lack of exsistance.
I believe that Palpatine was looking for someone as powerful as he was to help take over the galaxy and realized that the only one who could help him was himself. He couldn't clone himself because you couldn't clone the force(i'm talking movies only here folks) so he searched the galaxy for a way where he could procreate and yet keep the jedi from discovering that childs exsistance. So I believe he shared an intimate night with mama Skywalker and then used his dark side powers to make her think the whole thing never happened. This way if anyone ever tried to investigate where he came from, she would only be able to tell people he was the Star Wars version of Jesus and people would be like yeah, O.K. whatever lady, we have enough on our minds with this whole force thing.
I also believe that Palpatine was planning on going back for Anakin but he was discovered by Qui-Gon first and Palpatine was content with him being trained as a Jedi, so he could concentrate on the rest of his work while he would just convert him to the dark side once he was a Jedi Knight.
I know this sounds a lot like the whole Luke thing but it just makes sense to me. One son is kept a secret and is later revealed to be the son who goes bad, and it worked well enough at one point so why not do it again, with Luke only he won't go bad in the end. I'm curious as to what you all think so please let me know
