Revealing mistake: When Jenna is in her bedroom with her mom, as she points to the pictures in the article in Poise magazine, "30, Flirty and Thriving," it is blatantly apparent that it's not Jenna's 13 yr old hand in the close-up, but a much older body double. (00:05:25)
Revealing mistake: When Jenna and Matt are talking in the park and Jenna asks Matt to take pictures for the magazine. Everything is fine except that a girl in the background walking turns and looks directly at the camera and at both actors.
Answer: The rest of their lives...Jenna changed the future where she was 30 to a different one where her and Matt live happily ever after.
