Doug thought for a while. Amber said she didn't want to return, so she slowed down time wherever she came from. She was stabbed... He was hit by a bus. Both had traumatic outcomes. But she seemed like she previously came from a life of normality, a life of wealth perhaps. Would be getting medical attention. She said her body was waiting to die, but what if it survived, would she wake up? Or be a vegetable for the rest of her existence? No wonder she didn't want to go back. Come to think of it, did he really want to return to a life of homelessness, possibly now a life of disability and pain, with no medical attention or loved ones to care for him?
