Notes and Trivia
- This is the first time that Leo is shown in an Avatar's robe since he became one in "Someone to Witch Over Me".
- For the first time on the show, an episode different from a season premiere or penultimate episode ends with "to be continued" on the screen.
- The confrontation between Beta and Kyle is similar to the one between Leo and Kyle in "There's Something About Leo". Both Avatars attack with lightning as Kyle throws the potion. Both confrontations end in mutual destruction, though time was reversed the first time.
- The title is a reference to the ABC TV show "Extreme Makeover: Home Edition" where a group of people completely remodel someone's home.
- When Paige orbs out at the beginning of the episode, you can see through the page, because of sunlight, that it's on the Elders page. Yet, when Kyle goes to look for an entry on the Elders, he first flicks through the pages and then lands on the Elders page, which the book was already on.
- When Paige is sitting in Magic School, she is first wearing a pink sweatshirt, but after the talk of the Avatars, where she was not in sight, she wore the red top from the beginning of the episode again and the pink sweatshirt was not there anymore.
