Room 23 is a locked room in a facility within in the Hydra compound where Karl and Walt were held by the Others, and Karl was subjected to a brainwashing video. In 2007, Charles Widmore held Jin-Soo Kwon captive in the room. The DHARMA Initiative originally used the room to trigger amnesia in the Hostiles after interrogating them, so as not to violate the Truce. (EP) After The Purge, however, it was co-opted by the Others. (Access: Granted) The facility bears the Hydra logo, although it appears to be separated from the rest of the Hydra station. Room 23 is located at the end of a hall. The door next to it leads outside. Behind it is a stairwell because the terrain is lower at the backside of the building than at the front side.
