Ah ha! I found some inconsistencies. In the last book, Obiwan claimed that Anakin didn't know that his wife was pregnant and that only Ben and Padme knew about it and that if Anankin knew, he would come for the kids. I thought Anakin knew about the pregnancy and he had dreams of Padme dying from childbirth and he was tricked by the emperor into joining the dark side....He had believed that his wife's life would be spared...
Also uncle Owen wasn't Obiwan's brother. He was Anankin's step brother. Obiwan never knew his family. Jedies were usually raised from a baby in the temple and their only family is the Jedi order....is it just the book that is a mistake? I think after this, I want to watch the movie again.
