This episode the screen writers and the director seems a little off. It was a nice touch to show that they still celebrated Christmas in the year 2064 and the flash back to World War I when the soldiers fighting in it celebrated it also. For the second straight episode the 58th “WildCards” get caught behind enemy lines, this time in space. The miracle bit with the comet transmitting was a little too far fetched even in a sci-fi show. Another part is a marine using his hand to block a liquid oxygen pipe leak and the rest of the squad pulling his hand out. The way he still has his hand after doing this is unbelievable. His hand should have been broken off not just wrapped in bandages. This is far one of the worst episodes of the series.
