Continuity mistake: As Justin comes hysterically in to the restaurant from the lair, he runs over by the door to pull the shades down. A few seconds later when the camera is on Alex, you can see one of the shades is on the ground, However, after Alex says "you turned in your girlfriend to the Monster Hunter council" and Justin is shown, you can see that the shade has been put back in place.
Plot hole: When Justin and Juliet were trapped behind the glass and Juliet let herself be captured by the mummy, so she doesn't burn to ashes when the morning comes, why didn't Juliet just escape? The mummy gave her enough time to turn around and share a moment with Justin, she could've used that time to fight him off, break Justin out and escape. The mummy wasn't very strong and Alex would've shown up 20 seconds later anyway, there wasn't any real reason for Juliet to just let herself be taken away.
Continuity mistake: Alex's hair in season 3 changes back and forth between her shoulder length Bob and her long curly hair. The first instance of this is in the first episode with Mason in it. She had short hair in the previous episode, then it's long and curly in this episode, and then the following episode it's short again. This happens many times in season 3.
The Good, the Bad, and the Alex - S3-E15
Continuity mistake: When Alex, Justin and Harper find Stevie's brother, he tells them Stevie left the hall of transfers before he could become a full wizard. In season 4 when Alex and Justin become full wizards, they do not go to the hall of tranfers but are given full powers by the headmaster.
Answer: Honestly I've been confused too. Thought the ones going down went to Justin's bedroom or to the station. Then the ones out the door went maybe to an elevator to those stairs I guess. Then the one to the side went to the lair But the freezer also leads to the lair or a secret spot sometimes too.
I think the ones in the sub shop go right up to a hallway in front of the loft, then the ones in the lair go to the bedrooms upstairs. Now there's a way to get to the lair from the loft and I believe it would be past the kitchen down to the hallway where we don't really see except in like one episode. Now what confuses me the most is the lair because when Harper finds out you see Alex using magic to open it into the lair but in every other episode you open it and it's the lair.
