Penny was a patient at Grey Sloan Memorial Hospital.
When she saw Robert Fischer walking along the side of the road, she was distracted and ran a red light, causing a six-car pileup. When she got to the hospital, she was strapped to a gurney and conscious. She informed them that there was a very large cat.
Not long after that, Penny had to be intubated to help her breathe. The doctors then ran tests and operated to repair her injuries.
