The Interrogation Room is a location that appeared in the Webisodes.
During the interview of the old ARC, Lester, Becker, Matt and Jess are interviewed in the room. Matt and Jess are shown video footage of anomaly incursions.
Upon the return of Abby and Connor after their year in the Cretaceous they are interviewed by Matt in the interrogation room. Abby tells Matt about how she and Connor kept each other alive while Connor pleads with the new team leader to get him back on the team.
After the capture of Ethan Dobrowski/Patrick Quinn Matt takes him to the room to be interviewed on who he is and confess his plan on manipulating the anomalies. Patrick however reveals that he is not who Matt is looking for. Danny later asks his brother what happened to him and learns that Patrick's time traveling through the anomalies has disturbed him and turned him into a murderur. Patrick later asks Danny to let him go and that he promises to never bother anyone in this time again however Danny refuses. Patrick then knocks out a guard and holds Danny at gunpoint before promptly stunning him with the EMD. Patrick tries to kill Danny but realizes that he just can't do it.
Philip Burton watches video footage of Matt's interrogation of Patrick. Later on Matt tells Abby about his mission in a room that could possibly be the Interrogation room.
The room is a single small room with a see-through door. A single table and two chairs are in the room. There are no windows and there are multiple recording devices in the room which can be disabled. A computer that films people being interrogated/interviewed is usually on the table.
