Harsh Realm

Mike Pinocchio explaines that he carries a Heckler & Koch MP5K PDW pistol.

At the end of the scene were McKingley blackmails Stewart to turn the power back on, Hobbes' mouth can clearly be seen moving, though no dialogue is spoken.

When Tom and Inga are in the portal room a chair does not have headphones on the contrary to the one Inga uses to travel between worlds.

When Hobbes picks up the wanted poster for rebels in the Pittsburgh Encampment, he is looking at the front of it and then as we see it from the back it is plainly flipped as you can see through enough that it should have been reversed.

"Harsh Realm" was loosely based on a comic book by James D. Hudnall and Andrew Paquette under the same title. When the creators noticed the credits read "Created by Chris Carter", they sued Fox to get properly credited. http://www.agentassociation.com/frontdoor/news_detail.cfm?id=18

In this episode Hobbes carries a Heckler & Koch P7 pistol. Later in the series the gun was changed to the SIG Sauer P226 pistol and finally onto the Walther P99 which was used till the end of the season.

Inga Fossa is Latin for "in the trench."
