Pretty sure Claremont's lying about the coincidence. You don't do that sort of thing without having a future story in mind. However, that remark "Who am i to complain about other people being secretive? Old habits die hard" made me think she used to be a spy.
Scott is so much better when he's on his own or when someone else is in charge. :(
