Hall of Infinite Doors

You open the hatch and drop down to a beam under Nikita, probably used for maintenance. You walk down the beam when you hear the door from the right disposal facility clashing against the wall. Whatever was behind the door is ignoring you, for now. You decide to call Kaya. "Agent? Where the hell have you been, your radio was jammed. Whats the latest intel?" You tell her about Sokolov. "He was in command of Chimera's operation here on Nikita. You just weakened Chimera 's forces greatly." You start to tell her about the entity that has been following you. "Agent, you are probably just seeing things, from the excitement of battle. Your mission objective is to escape now, well done, primary objective complete." (Click) Its time to get off of Nikita, but you cant cease to think about the thing that contacted you. Is it just post traumatic stress forming an illusion or was it someone...something that wanted you?
