Padmé is preparing to attend a conference hosted by Senator Bail Organa on Alderaan , which is to address the increasing humanitarian problem of the war refugees .

As the conference begins and Padmé makes her speech , Ahsoka ' s fears come true : Aurra Sing has indeed smuggled herself into the conference building and is preparing to kill Padmé . Ahsoka arrives just in time to prevent Sing from hitting Padmé dead on target with a sniper blaster , but the senator suffers a shoulder wound and Sing manages to get away .
