Character mistake: When Allison falls down the stairs her fiancé says "EMILY!"
Suggested correction: He shouts "Ali", short for Allison, not Emily.
Suggested correction: He shouts, "Ali" which is short for Allison.
Character mistake: Ali calls Emily "Hannah" when getting to the romantic spot that she set up.
Suggested correction: Ali doesn't call her by any name. I think what you're hearing as "Hannah" was the line "and if" (and if this is our last chance of freedom). Or before when she said "I had a dream."
Factual error: While talking on the street, Hanna and Jordan walk into a store called Rosewood Grape Wine after Hanna tells him that she's not going to Allison's without food. However in Pennsylvania, nearly all wine by law is sold in state stores, called Fine Wine and Good Spirits. (00:14:20)
Suggested correction: Rosewood, Pennsylvania is a fictional town. The show can therefore do whatever it wants.
