Board Thread:Mirror of Fate/@comment-21823483-20140324221535

I am curious to know where this information that states where the brotherhood handed Simon over to the tribes. because i remember in the cutscene at the beggining of Mirror of Fate (showing Sypha and Simon fleeing the assault on the fortress). Simon was alone with his mother as they managed to escape the destruction. There were no Brotherhood members with them. Can someone clarify this for me, i thought the Brotherhood didn't know about Simon until after he succedded in his quest?
