Where does this employee’s injury fall in the gray area of what’s eligible for workers’ comp?

Q: “We allow our managers to work remotely from home and to only report to the office once or twice per week. One of our managers spent the night with a friend, did some work on her laptop there the next morning, and then got into a car accident on her way from the friend's home to the office to pick up some paperwork. Would this accident qualify for workers’ comp or not? She wasn't traveling from home to work, but she also wasn't traveling from work site to work site (in my opinion).” – Janet, North Carolina
