There is a lot of coughing, not just Burt and Victor (Otto Sturcke even coughs throughout his We're Not Dead interview). Characters can be heard coughing in the background as the guys walk to and around the watch towers. Of course this could be KC's way of portraying the was weary. Also, there wasn't a lot of coughing at the arena, but............ CRAP! Did I just shoot down my own Zombie Cough theory? UGH, it's bed time. G'nite y'all.
