Don ordered Elliot and Olivia to go undercover as nurses to keep an eye on their deceased John Doe to find out who he was and what happened. At St. Mark's Hospital, Elliot had to make a phone call.
Elliot: I'm sorry, there's nothing I can do about it. Yeah...Bye
Olivia: Something wrong?
Elliot: Kathy. We were supposed to have a drink tonight. I'm moving back home.
Elliot: We haven't decided. That's why we were going to have a drink.
