When Yuri is taking a shower (around the 58:16 mark), her hair is all soapy with shampoo and is on the top of her head; the very next moment it appears all rinsed, down around her shoulders and only damp, not sopping wet.
When the kid enter the house, after being threatened by the other 3 kids, he then leaves the house and throw a rock at one of the kids. The rock obviously doesn't hit the boy, and he is smiling in the scene.
