Episode #1.7 - S1-E7
Factual error: When Marie is talking with her therapist, she talks about having just gone to see Zombieland. Given that the scene takes place in 2008 and Zombieland wasn't released in the US until October 2009, this simply is not possible.
Suggested correction: The series starts in 2008, but it's 3 years later. At the beginning, RoseMarie says Curtis was born February 3, 1981 and is 30 years old.
The therapy scenes are in 2008. It's only when the photographs of Marie are discovered that we see Marie 3 years later, in episode 8.
