I had a little trouble following this story, the flashbacks threw me off a bit but that's just me, way too literal finding zig zagging time frames difficult to keep straight. But one thing I noticed for sure when the BAU and local law enforcement busted into that torture chamber of a trailer. Can anyone say David Parker Ray? I can't remember the details in terms of year or exact location (other than the Southwest) but a serial killer named David Parker Ray lured an untold number of women to their deaths in a trailer much like the one shown in this episode. I'm not implying any issues with this, so many tv and movie scripts are based on real life characters. DPR had a torture chamber complete with those mirrors on the ceiling, the medical grade saws and other tools for dismemberment - all in all just chilling to the bone - ooh! Probably not the best choice of phrasing here! If you know nothing of DPR and this stuff interests you or gets to you whichever rings your bell, do some internet searches. It's mind-blowing.
