Around 22:40, Olivia is coming out the back door of her client and Harrison and Abby are waiting for her outside. There's a shot of Abby's and Harrison's back, and you can see Abby putting her purse on her shoulder and checking her watch, and as Olivia comes out and we see the front of Abby and Harrison, Abby puts her purse on her shoulder and checks her watch for a second time.
