I was listening to WA Lockdown again and I noticed something that confused me near the end of Part 1. Throughout Simeon's retelling of the events, we hear Mark, Dani, Gavin, an unnamed male guard and maybe another female guard (who leaves to get Austin from Solitary?). Gavin goes off to get more carbon printouts from Block 7 and Dani returns with Jodi. As the alarms are going off and the inmates are locked back down in the holding cell, the unnamed guard is heard one more time at 50:25 "We're all good over here". A few seconds later Mark yells "LOCKDOWN!"

What I don't get is that with the complete lockdown of all the doors, where did that third guard go? He couldn't have gotten all the way down the hall and out past the electronic door so soon. Am I completely missing something?
