Other mistake: According to reverse-time issue: In court, when Quinn looks at the clock on the wall, you can see that the clock still goes forward, despite of the anticlockwise indicators since the digits are inverted. (00:31:25)
Suggested correction: You just explained the plot that Max explained to the group. Time is moving forward to the people of that world but moving backwards for them. So the anti-clockwise movement of the hands show time moving backwards while the reverse order of the numbers shows time moving forward.
Trivia: The man who is homeless in "our" world, and is running for the U.S. Senator in the parallel universe, is the episode's director, Andy Tennant, making a memorable cameo appearance.
Suggested correction: The homeless man (Crazy Kenny) was played by Frank C. Turner, not Andy Tennant.

Plot hole: Quinn is unable to touch anything or anyone, yet he is somehow able to sit in a taxi cab. Why doesn't he fall through the car seat?
Suggested correction: This is a common trope with ghosts or people on the astral plane or out of phase. It's not a mistake since it's not a real life thing and it's not explained how it works (although there are some theoretical physics theories behind it). He can sit in the cab the same way he can walk on the ground and up stairs.
