- When Sadiq and the others exit the mine, they find the "The End is Nigh" sign, which was being held by the doomsday man, on the ground. However, later when Reese is watching the CCTV footage, some of the adults can be seen holding objects and they vanish along with them. (It's possible the man put his sign down for some reason.)
- Doomsday Dora says a couple of episodes later that humans cannot be duplicated, but objects can. Why then are the clothes left by the adults not duplicated and just vanish with the adults?
