In the beginning of Captain Jim Bob Sherwood, Justin tells Alex he doesn't use email because spam tries to sell him vitamins, and Alex seems quite amused to find that Justin ordered some. It was an obvious 'male enhancement' joke. The brilliant part comes when you realize Justin has confessed to Alex how insecure he is during the movie.
Future Harper. So many throw away lines end up becoming major plot points.
One might think the writers dropped the ball when Dwayne Johnson, delivered the line "Acting is my first and only job.", forgetting that he got his starting in Professional Wrestling...that is, until one considers that Pro Wrestling as we know it today is acting.
An answer to the often asked question "Why is Stevie's plan bad?" If the roughly 5000 other wizards who joined her revolution are anything like her, they probably have no qualms about using magic in front of other people. (Remember that hole-in-the-ground spell Stevie cast in the middle of a hallway full of Muggles?) In addition, Stevie often demonstrates a callous lack of regard for the impact of her actions on others. (Again, the hole-in-the-ground spell. By her own admission, she neither knew nor cared where that student ended up.) Imagine what would happen if her followers were to go around emulating her behavior. There would be a huge risk not only to innocent bystanders, but to the secrecy of the Wizard world as a whole. This, in fact, is probably the whole reason why the Wizard competition exists in the first place: To weed out those Wizards who don't display enough competence or concern to use their powers without exposing wizardry to mortals. Think about why Alex won: She displayed intelligence and creativity during the competition itself (Remembering spells and coming up with clever ways around obstacles) and she displayed loyalty and concern for others. (Going back to help Justin, even though it meant sacrificing her victory.) Even though she sometimes messes up and engages in reckless behavior, it's balanced out by her having the qualities that make a person worthy to be a wizard. Stevie doesn't have those qualities to balance her out and her followers probably don't either, so if they were allowed to keep their powers, they'd probably act in a way that creates a serious risk of wizardry being exposed.
Max is often called a Villain Protagonist on This Very Wiki because of the time he freed a bunch of dangerous monsters just to thwart Justin. But think about the spell he had cast just moments before. He made his conscience into a separate person. In other words: he took it out of his body. Of course someone without a conscience is going to act more recklessly than they would otherwise.
Although, from that same episode... when the Moral Compass was set to evil, one could see Jerry, Theresa, and Harper all take a level in Jerkass. But, we normally know them as nice people. How could it have affected people who are actually jerks, or even those who are evil? Who knows how much of the world it could have affected? There could have been Moral Event Horizons happening all over the world, all because of Gorog.
Mason eating Dean alive, while he is not in his full werewolf mode, actually implies THIS.
Non-wizard humans are nicknamed mortals + The longevity of Professor Crumb = It might not be just power at stake in the wizard competition.
Actually more of Fridge Squick, but to get that dress on Alex that little girl would have needed to take her old clothes off first.
After Ian Abercrombie bit the dust in early 2012, his character passing his position on to Justin may now wind up becoming Harsher in Hindsight due to Actor Existence Failure happening just days after the series finale was broadcast.
In one episode, an Animate spell causes a store mannequin and a CatwomanExpy to come to life. The spell specifically forbids the spell from being dispelled if the target develops emotions. Why? It's never specifically stated, but it can be inferred that these creations have personalities, emotions, and indivuality. In essence, they have souls. So, when Manny the mannequin gets dunked in water, the spell is dismissed, conveniently fixing the "problem" of the ep. Didn't they just strictly forbid the spell being ended? If we follow the inference that Animated beings have "souls," does that mean the jealous boyfriend who dunked Manny just committed murder? Yes, absolutely.
In The Movie, during the wizard competition, Alex wins through making Justin slip in mud repeatedly and teleportation. Justin, on the other hand, put up a wall of fire and made Alex melt in order to win. In other words, Justin is willing to put his sister's life in danger to win the competition. Kinda makes you question which one is the "good kid."
In "Wizards vs. Werewolves", Max defeats the Mummy by unwrapping it. How does that work exactly?
In the movie, Alex wishes for her parents to have never met while holding the superpowered family wand. After the wish comes true, the wand ends up with her dad, whom she later sees again, although he doesn't recognize her, and yet it doesn't occur to her to ask him to borrow the wand and wish for her previous wish to be undone.
