Part two of two. The repercussions of the crew's discovery and Dr. Hilbert's actions continue to disrupt the station's Christmas plans. Cut off from Minkowski and with limited time to act, Eiffel decides to take a risk. Plus, Smokey Bear Mode, Mr. Kettle, giant fireballs, laughing gas, and crazy plans. 

Part one of two. It's Christmas Day on the Hephaestus. While Minkowski does her best to approximate a traditional holiday dinner, Eiffel decides he's going to try to smoke his last cigarette. Both plans are put on hold, however, when Dr. Hilbert stumbles upon a major discovery. Plus, impenetrable darkness, the blunt approach, sanitized pagan rituals, caller ID, and the last of the real turkey.

In a set of short stories, we get to see what the Hephaestus crew does when they are by themselves. Doctor Hilbert tells a joke and ponders a question. Hera plays a game. Eiffel takes a test. Minkowski sends a message. Plus, floating on a tin can, magic lamps, disappearing terrarriums, programming loopholes, and the HAL 9000 touch.
