Sera dragged him over to the conveyor belt line, which sorted materials by substance. There were people, prisoners, that worked each station. Sera then stepped back, turning on her heel and walking around, watching the prisoners and ensuring they were working

Sera continued her rounds, ensuring that everyone was still working. IT they weren't her fire would burn close to their neck

Sera made her rounds, watching as they worked. When the man came back in to do a check up, his keys were hanging out, in Finn's reach. He talked with Sera and the other guards, mentioning the names of Finn friends as well, who were also working down the line in the conveyor belt

Sera continued her rounds after the man left. The keys the man did not notice were missing held the opening to every room in the place, as well as the keys to unlock the shackles

Sera continued to make rounds, her fire at the ready.
