Being summoned by a superior always happens at the worst time.
So use it in a game! Lex Luthor has just revealed a nefarious plot to join forces with General Zod and lay waste to Metropolis... and Perry White calls Clark Kent into his office - pronto! - for an important discussion about what's happening to the quality of the sandwiches at the Daily Planet. And Kent better listen up and listen good, because White's pretty peeved!
GM: Let's start with a Darth Vader scene. Annie, Palpatine has summoned you.
Darth Vader: Why have you summoned me?
Palpatine: Past all thought of right or wrong; one idle question.
Darth Vader: This being?
Palpatine: She believes she dines with me; in her master's borrowed place.
Palpatine: Slowly, then, your life support surrenders. Grasp it, sense it, helpless and defenceless.
Darth Vader: My lord.
Palpatine: A disturbance in the Force...
Palpatine: Wandering children; so lost; so helpless; yearning for your guidance.
Palpatine: What are they doing on the Moon?
Darth Vader: Being rounded up and captured. Of course.
Palpatine: Sad to return to find the Moon we love threatened once more by Rebels' far-reaching grasp.
Darth Vader: This Moon is much larger. And has a defence station.
Palpatine: It is vital they do not disturb the ecosystem. You will curse the day you did not do all that the Emperor asked of you.
Darth Vader: The only reason I am not there now is because you summoned me here.
