Revealing mistake: About twenty minutes into the episode, Tru sits down next to Jen. Jen says, "I saw you in line in the cafeteria." Tru, with her hands at her sides, says, "Tru." Jen says, "Jen," and raises her hand to shake, at which point Tru reciprocates. But how did Jen know that Tru was introducing herself? After all, pretty much nobody else is named Tru, so in context it would have sounded like Tru was saying, "True," as in, "True; you did see me in the cafeteria."
Revealing mistake: It was raining in Vancouver the day the outdoor scenes were filmed for this episode, so the actors were filmed under large tarps. When Tru and Paige walk together in the park, rain can occasionally be seen in the foreground and background, but not over the characters themselves. The ground is also wet everywhere throughout the episode.
