Very briefly in the beginning of the film, during the swimming scene, the little boy is having a hard time swimming. Then about 48 minutes in, two characters gasp for breath after being submerged underwater for maybe a minute.
There is a scene maybe 14-18 minutes into the film where someone is tattooing a child with a tattoo gun. The child seems to want the tattoo, but he winces and bleeds a little. It doesn’t seem like he is being tattooed against his will, but he is like, eight to ten years old.
