Ewan, your Cathedral contact, said he'd call you when he'd taken care of some housekeeping, so don't expect him to call for a while. In the meantime, the case file said your first priority was to track down Moira Chisolm, who worked with your Mom on the Colony case. That's your priority.
As you leave your room, you'll meet the goofy Bridget. To get outside, go down the hall to the elevator and press the G button to go to the ground floor. (In the UK, the first floor is the ground floor, and the second floor is the first floor. If you care.) In case you missed it, Nancy's room is 727, so she's on the seventh floor when you want to go back to her room.
