The man the camera zooms in just after the extinguisher beating, who smiles? That is Le Tenia.
Just the realization that this happens in the real world.
Also, one of the most disturbing things about the rape scene is how methodical Le Tenia is; there is no hurry or uncertainty, he knows exactly what he's doing, as if he's had a lot of practice...
The scary thing is, pimps in Real Life often rape their prostitutes to "break them."
