HTV Interview: Nico

"Where are we going?" I ask as I get in, pulling on my seatbelt out of habit. He doesn't bother to put his on.

"The Hall."

I unbuckle my seatbelt, planning on getting out again, but he looks at me. "If you don't go with me, you'll wind up talking with Mastermental on your own," he says plainly. "Do you really want to do that?"

I look at him for a long moment, picturing a meeting with Mastermental without anyone else there. What would the head of the Hall do to the daughter of Mimic? He's a telepath, right? All sorts of freaky mind powers—he could wipe my memories or— "I don't need to talk to him," I say.

"You do," Nico says, "because otherwise I won't be able to get you in to see your old man."

It starts out simple—a visit to a father she hasn't seen in years, but when your father's a super villain and your roommate's a time traveler, things never stay that way.
