In the most recent "Old Republic" novel (the one currently in hardcover), one of the main characters is the son of Satele Shan, the Jedi Grand Master. I'm curious to know how that came about without Satele being ejected from the Jedi Order. I doubt it's a secret son, since Satele seems to be a rather straight-arrow type, devoted to the Jedi Order.
Actually, Jace and Satele's son was a secret delivery and they gave the child to a Jedi Grand Master to raise. As for being ejected, if she showed no signs of giving into the Dark Side, no one is going to question a Grand Master.
