Did anyone else think that Danford bought some of the bread?
Before the boy is hired to buy the last of the bread, a female stops at the table and purchases some of the last loaves. She engages with the girl - calls her by name - and asks about her mother. Unlike any of the other buyers, we never see her face and just her hands which, unlike the other shoppers, doesn't appear to be dark-skinned.
I noticed at what is supposed to be this same point, when the film shifts back to the control rooms, in the background the bug camera is showing on the screens the live feed from inside the house. The males are getting ready for their supposed suicide attack and being filmed giving their last statements, but the female (Danford) does not appear to be in the room at this point.
I think perhaps the viewer is supposed to assume that Danford actually bought the bread. It might make sense that she's been to this safe house before and purchased bread from the girl in the past. I thought it was one of the few subtle touches in the movie, which helped to portray the "villain" as a multi-layered person and not just all-encompassed evil. Actually, now that I think about it, the movie was a little too heavy handed in a lot of parts so maybe I'm giving the filmmakers a little too much credit here, and maybe it wasn't supposed to be her.
