The scene that you bring up is a whole 2 seconds

two seconds long ... Jeroen afterwards is happier then a pig in mud... Facial Idiosyncrasies of someone trying a new food, of lifting weights to get ripped, a downhill alpine slalom skier taking a bend down the hill, a motocross biker taking a jump, or a male youth feeling a sexual exiting tension... they are all (activities) going to translate into a facial expression/tension/or a multiple of said "communicative" expressions. You bite into a frozen ice cream sandwich... fist it's the ooouh that's cold then the yum (big round eyes), then the big smile of that feels good going down, and tickles the taste buds. The following scenes in F.A.L.S are what makes it great, Jeroen is happy, proud, he clings to the photo of Walt and puts in in his pocket, as he proudly slicks back his hair with a comb..the little patty-cakes scene with them singing some weird song etc... The entirety of it all suggests no foul play to me. Also Walt strokes his hair/head very gently, calls him his prince demonstrating very deliberate slow and gentle love making. The problem is that only 2 seconds of this "entire sexual scene" was shown... what happened 16 minutes before?, and 21 minutes after that exact scene? The problem with a movie like that is that it can truly educate, or demonstrate the joy, without it being a criminal film. Anyway, that's my interpretation. They truly were loved by each other, and I think the father came to understand/accept it too... Too bad 16 more movies like it haven't been done :(
