Zim jerked his head up in surprise but his surroundings hadn't changed in his pain induced sleep. Same plasma walls, same feeling of dread, same same same.
Zim checked the automated calendars in his PAK. It was a Tuesday in Earth time. Tuesday was an observation day, though Zim didn't know what they could find that they hadn't already discovered.
Humans were creative for coming up with ideas for torture. The Irken was all too aware of that fact. They called it science. He called it painful.
When he was first taken here, Zim tried to self-destruct. He forgot it had been broken for a while.
A chunk of twisted metal and wires slid through the wall to him. The humans wanted him to fix it or make something of it. Human technology was pitiful, crude, and wasteful. So much metal to make anything when a dozen better, faster, and more efficient things could be made from the same material!
This chunk of metal was one of the more useful ones. Zim still had sensors all over the Membrane labs that were fully operational. He secreted the parts that to human eyes seemed dysfunctional or broken but to Zim seemed perfect for his PAK.
PAK work was delicate and deadly, but necessary to ensure his escape.
