a new take on this?
I have different ideas about what happened at the end. People might say that I am taking too much from what was shown, but it's the only logical explanation I can think of!
Here goes:
I thought that Paco killed the girls. Chantal loved Paco, and didn't know that he killed them...she actually thought it was Henry. Henry knew it was Paco,and thought Chantal knew and was trying to frame Henry, so confessed to the killings so that Chantal could be with the man she loved (Henry was devoted to his wife even though she couldn't show her love for him [as she thought he may have been abusing children]).
I thought that at the end we would have seen Victor confronting Paco in the station, and clips of Paco putting the pictures in Henry's dark room. But as this didn't happen, I'm confused! I probably made too much of it.
my 2 pence worth anyway.
