(at around 22 mins) When Rebecca and Martin are in the kitchen Rebecca places a milk jug on the table, milk instantly appears in a glass and the amount is constantly changing through the entire scene.

The condition Diana has is called Xeroderma pigmentosum, which makes the skin hyper sensitive to the Ultraviolet rays of the light. But in the movie we see Diana being okay with Blacklight/Pure UV light. UV light should be rather more dangerous to her with that condition than normal light.
(at around 14 mins) When the social worker is talking to Rebecca, she asks if Martin is her brother. Rebecca responds that they are step-siblings. This is factually untrue since we learn later on in the movie that they both have the same mother. Therefore, they are half-siblings, not step-siblings.
Rebecca identifies Martin's father as her stepfather; she never calls Martin her stepbrother.
