不絕

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

绝 = 纟 + 色 : Just inside the elevator's kitchen Zeus and the silk worm are playing a dice game. The game is called "annihilation", and the loser is said to become extinct within 1000 years' time. They don't know yet that both gods and worms will be extinct due to the human race soon.
