After Brooke hung up the phone, she followed James' reasoning, saying she needed to take Jane back to deal with her wound, and requested to leave here with the person in charge.
Jane is pregnant, and it's a well-known fact that she's injured, so even though there's no result yet for the theft case, the person in charge here didn't dare keep the Black Family people, fearing the consequences if Jane indeed got an infection, which would be too much for anyone to bear.
Brooke easily took a few people out like that.
With Quincy and Jane not around, Amber was lazy to wait and ended up leaving with her brother, following Jane and the others.
The driver was in the car, and after seeing Jane and Brooke get in, he started the car, drove out of the guest house, and just then expressed concern about Jane's wound.
