Factual error: In the first episode of season two you see Teresa with Ryan, yet she has no bump. Season one ends at the end of the school term and season two starts off just before the school term. Therefore there's been about two and a half months of school holiday plus the time between her sleeping with Ryan and discovering she's pregnant and Ryan leaving for Chino with her - therefore she should be showing some signs of pregnancy in early season two.
Factual error: How exactly does Seth unlock the door? The entire purpose of locking the storeroom is to keep mall customers out so they won't steal things, not to keep people in there, so there is no way it was only lockable from the outside. If it was a key operated lock, why would someone just leave their key in the keyhole for someone to take? There is no explanation for Seth being able to unlock the door.
