Don't know if anyone else has come across World War Z, basically one of those "this is what I did in the war" collections of personal accounts, only it's about a plague of zombies trying to destroy mankind.
We never really saw Clark dealing with something like that, and it doesn't really seem the sort of thing his powers would be good for - maybe keeping the zombies out of a defended area such as the Planet building (but is someone inside the building infected?), flying food back to the besieged survivors, etc., but it's probably something that can only be solved by doctors - Clark can help, but he can't fix it alone.
Anyway, the challenge is to write an account of World War Z from the L&C viewpoint. Preferably without anyone eating Lois's brains...
