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: Emily is supposed to meet Paige at a karaoke bar at the intersection of 202 and W. Chester Pike, however this intersection is actually an overpass. 202 crosses over top of West Chester Pike, but never actually intersects it.
