Those Hurley numbers keep appearing. In the season 3 episode "The Glass Ballerina" 27 minutes into the show, Jin confronts Jae in the hotel. Even though he clearly gets off the elevator on the 2nd floor, Jae's room number is "1516". Of course, this is part of the Hurley numbers 4,8,15,16,23,42. In another egg already listed for "Exodus Part 2", Hurley stayed in a hotel room #2342. Seems to be a recurring theme.
