In the hotel room, Simon tricks the thugs so they check out the bathroom, Simon then locks them in from the outside. Bathroom doors always lock from the inside, never the outside.
Simon is shown float fishing at the beginning of the episode.
As the camera pulls back we see a fly fishing rod and reel. A float is never used whilst fly fishing. The rod/reel shown is only ever used for casting an artificial fly onto the water surface.
In the opening scene, as Mildred's mini races towards Simon, a tyre screeching sound effect is heard. However, the road is a gravel and dirt track so the tyres wouldn't make a screeching sound.
