Sebastian and Jace hid in the apartment while they had a bond, and since it exists as a pocket dimension they could not be tracked. Sebastian took Clary to the apartment when she joined them, acting as a spy. During a physical fight between the two, Clary managed to get a stele from him and drew a rune on what was supposed to be the door. Sebastian saw this as an unfinished opening rune and laughed at her silly attempt. After they got ready and left the apartment exploded. Clary laughed and explained that her 'unfinished' rune was actually completed to destroy the place.
