Revealing mistake: In the scene after the fire, when Kyle is playing with a candle, as he picks up the candle his belly button is visible. It has been established that Kyle has no belly button, therefore this is a mistake.
Continuity mistake: When Kyle drives away in a car, the logos on the trunk disappear and reappear from one shot to the next. (00:34:55)
Continuity mistake: Lori and Declan are making up - the wall behind them changes from a brick wall to a wall made out of porous concrete as the light goes back on. (00:40:05)
Plot hole: When Mr. Ballentine is telling Emily about her assignment, he sets the blue folder down near his side of the desk before he gets up. Then we see Emily pull it across the table and quickly peek in it. When Ballentine turns around, the folder is still close to Emily, which shows that she at least tried to look in it, yet Ballentine says nothing about it no longer being in the spot where he set it down. If Emily thought that it was okay for her to look in the folder, she wouldn't have waited for Ballentine to turn around before she touched it.
Factual error: In the episode where Kyle, Lori, and Josh first go to the pool together, Kyle jumps off the diving board, but he's only in the water for about three seconds before he sees Amanda, who is already swimming toward him. This means that he was in the water for just a second or two before she jumped in. That isn't enough time for anyone to appear to be drowning, especially to a trained lifeguard like Amanda.
Suggested correction: First, at least 10 seconds pass before Amanda jumps in, not 1-3 seconds. But that doesn't mean only 10 seconds passed in the show. But additionally, Amanda already knows Kyle has memory loss and could be thinking Kyle forgot how to swim or forgot that he can't swim. So she goes to get him.
Continuity mistake: In the bathroom scene, Andy's hat keeps changing position between shots. Her hat position interchanges between showing all of her forehead to none of it.
Continuity mistake: When Kyle is taking the test, he's doing it with precision and accuracy, but he marks the wrong answers for #31-33. Even though it's meant to be a continuous shot, when he's answering #35, his answers to #31-33 are now changed to the correct answer. Kyle is able to answer the questions right the first time and didn't go back to change his answers, plus there's no sign of the previous marks if they were erased.
Character mistake: When Kyle is re-taking the test at the end of the school day, you see him bubble in 4 answer and turn the page and continue to answer questions. However there were 7 questions on the first page so he ended up putting the answer to #8 on #5 of the scantron. Kyle is too smart to do this.
Plot hole: About three and a half minutes into the episode, Kyle looks through the photo album and sees a picture of his fake mother (the woman paid to pretend to be his mother) giving him a dog for Christmas. Two minutes later in a different scene, the paid parents claim in front of everyone that they're both allergic and had no pets. So by now it's obvious they're lying. Another two minutes later in another scene, Kyle's foster parents are looking through that same album and nobody ever notices the inconsistency.
Continuity mistake: This is actually both continuity and character mistake error. In the scene where Kyle helps Josh with his math test, the first time we look at the test, Josh has stuck in problem number 3, and in the problem above, number 2 has already given the answer "A". The second time we see the test, they jumped in problem number 13, which ironically in the previous shot was half covered with the kid's hand, so obviously he couldn't look at it. Also he has now answered question 12 above as well. Moreover Kyle says the correct answer is X=49. It's a complete random answer that has nothing to do with either question 3 or 13. In question 3, "X" isn't even mentioned and is just a multiple choice between A and E. In problem 13, if we do the math, we have X. (00:16:15)
Revealing mistake: When they shine light through the Zyzzx ring, Kyle walks in front of it, but the map is still visible on the wall. Meaning that it's either added in editing or the light shines from another source.
