Continuity mistake: In this episode, Lily's golden sprite tattoo is underneath the name "Dean" - "Dean" is written above the sprite's head, between the tips of her wings. A few episodes ago, at the end of "Your Father Shoulder Know - Part 2", Sean hugged Lily and accidentally lifted the back of her shirt, revealing the tattoo. The name "Dean" was not there.
Continuity mistake: In the episode where Eddie first gets his blue electric car. He plugs the car into the kitchen with a long red extension cord. When there's a shot of Claudia first coming out of the kitchen to see what's going on, the red cord is gone. The whole kitchen entrance is shown, so the red cord should be visible. Then, when Eddie and Shawn are shown again, the red cord is back on the floor behind them.
