I've had a blister on my brain about this for a while now, and I need to get this off my chest. Someone may have already pointed it out, and bear with me, but I'm not good with ep titles.
Chronologically, Ben came into Rousseau's tent and stole Alex, right? Wouldn't you remember the man's face who stole your child? It wasn't a snatch and grab by any means; Ben looked at Danielle and told her if she hears whispers to run the other way.
Then, in season 2, Danielle catches Ben in a net (which I still think was intentional on Ben's part - what, was he just roaming the jungle?) and fetches Said to investigate. How can she NOT remember Ben stealing Alex?? She tells Said he is "one of them" but obviously forgot (?) that he was the man from the beach the night of Alex's abduction. Re-watching that clip when Ben is caught in the net tells me that Danielle has no clue that this is the same man.
If so, she would definitely have shot and killed him on the spot, after torturing him to get info on Alex's whereabouts... not just given him a puncture wound with an arrow. Then she lets Said take him to the Hatch to interrogate him. She is (was, R.I.P.) way too smart for that. Maybe an overlook by the writers, but hey, I had to get that off my chest.
