"You wanted me to come to this place," you say. "Why? Be specific."
Zara nods, then says, "We would like two things of you. The first is your friendship. Please, let us help you go back to your own time. And when you're there, think favorably of us. The year you came from…it was the month of June, was it not? A small number of us are already in your world. One of our agents will approach you soon. When he does, be open-minded. Greet him with a sincere smile."
That sounds simple enough. "And the second?"
"Please hand over the Zapp Sapper," she says. "We have manipulated your friend Mekk into bringing us this artifact. And your own arrival here was not unanticipated. Yet it is an unfortunate coincidence that your paths have coincided. The Zapp Sapper is a powerful device, one that does not belong in your own time. Give it to me, and the Surgeons will reward your good grace." She gives Mekk a significant glance. He is still lying curled up on the floor, in pain, dying.
