When he shows Lana by shooting his hand, they start talking by the stained glass window. The reflections in their eyes are supposed to be the light coming through the window, but are actually from a white screen used for lighting. The reflections in their eyes are rectangular to confirm this.

Question: How realistic is Lana's physical therapy scene? She says she broke her leg in 4 places and hasn't walked in a month. She's seen struggling to walk using the metal bars to support herself, which Adam seems to suggest she could do "another lap" but that she quit. But then after struggling to walk, she's given her crutches and the therapist leaves, leaving her to walk on her own with crutches. If she struggled with the bars, could she use crutches? Or would she be in a wheelchair?
