Near the beginning of Episode II, when Obi Wan has jumped out the window and is hanging on to the droid that tried to kill Padme, and the assassin sees the droid and Obi Wan coming towards her, why the heck does she shoot the droid? Wouldn’t it have made much more sense just to shoot Obi Wan? But I guess then the movie would have been over.
On a related note, perhaps she could have asseverated vertiginously with a dichotomy of pulchritude.
