Goofs

After first being in Coventry, Alex runs back to the closet door portal with Camryn running after her. Beside the door are the files that Camryn dropped beside it earlier. However when the door flies off into the sky the files have vanished.

After Alex steps off the bus at the same corner as Camryn and Beth, some of the same extras keep walking past in quite a few of the following shots. Two examples are the woman wearing a striped top and black skirt, and the man wearing a plaid shirt and tan pants.

After the twins see a bit of Coventry for the first time, in Camryn's bedroom, when she pleads with Alex not to leave, in the close-up Alex has tears in her eyes and her black eyeliner is nearly gone. When she turns around in the next close-up her eyes aren't even moist and her eyeliner is perfect.

Camryn leaves her photo albums behind after leaving Conventry for the first time.

When Alex is standing in front of Camryn's wall covered in drawings, while Camryn is searching through her closet, Alex's purple headband appears and disappears over her left shoulder a few times between shots.

When Ardemis is playing with the birthday cake that Lucinda made for her, the piece that she has on her plate has an 'A' on it. The actual cake still has the 'A' on it though. The piece that was taken from the cake should have the 'LEX' on it.

When Cam is blowing out her candles, you see that one of them blows out on its own, after Cameron stops blowing.

During the birthday party scene, Tia who plays Alex is playing Tamera's character Camryn.

When Cameron first brings Alex to her mansion and yells for her parents, Alex says something that sounds like "Tia, no!". Tia Mowry actually plays Alex, and her sister(Tamera Mowry) plays Cameron.
