The human body is amusingly fragile.

The sound of the slow heartbeat from the monitor was equally soothing and dreadful in Dominic's ears. Sitting beside the bed in the intensive care unit with complete hospital gear on, he kept his eyes on his wife. Different apparatus were injected into her to support her breathing and monitor her vitals. 

Initially, he heard that she had jumped out of the car. But from what Moose said, he deduced she was probably thrown out because of how bad her fall was. Jumping out of the car was dangerous, but they said if she had done it on her own, she would've anticipated it and was able to reduce the damages. 

But her injuries told them otherwise. 

Heaven hit her head with something and because of that, she ended up in here. Amusingly enough, that was the only fatal injury she got. Just one major injury, and she's threading in between life and death.
