Although this question is of an easy answering, it also poses a question I had here on this forum, which I'll bring up again just for the fun of it. Leia obviously knew who Vader is, and their brief dialogue as her ship is boarded suggest they've met and talked several times before. Wouldn't it be a little risky for Bail Organa to expose Leia to Vader that easily? I mean, he could somehow realize that was Padme's daughter.
