Gaz awoke blindfolded and in some sort of liquid with her arms and legs tied by what felt like thread. She was about to give the bonds a good hard tug when she heard a voice.
"Don't bother," it said." I made them myself."
That voice. "If it's anything like that containment chamber you put my brother in, then I have nothing to worry about."
"You still think of me as that sad fool who couldn't make a proper disguise, I see," Zim said. "Nobody ever suspected something more sinister than the simple takeover of a backwater planet."
"Well if you aren't the Zim I know," Gaz said, wishing that the bonds were gone so she could ring his green neck, "then who are you?"
"They all asked the same questions, you know," Zim said, sounding board. "It's always 'who are you', 'why are you doing this', and 'where am I'. It gets mighty monotonous at times."
"You still haven't answered my question."
"Ah yes, who am I. You know my name, but not my past. I assume that is what you are after. But before I explain that, I will tell you something else. At the moment you are being both mind and will wiped. Wiping of the mind is fairly simple and quick. The only thing you will be able to remember of this is the sound of my spider legs. The will wipe, however, is slightly more difficult. It takes a few hours for most humans. That's why you're here.
"During my 'secret mission' on Earth, I watched you and your brother. You two are obviously not normal humans. You both have wills stronger than, as you humans say, steel. Yet even steel can bend and break. Yes, I've found your strengths and weaknesses, little Gaz. If I can break both you and your brother, than your species will soon follow.
"Now about my past, I'm afraid I can't take any chances with you. If I told you and you somehow escaped, you would hold a major piece to the puzzle. I won't make mistakes like the Zim you knew would. Good night, little Gaz, and remember. Your brother will soon follow you."
With that, Gaz was surrounded by pain.
