Character mistake: When Jesse and Becky are in the living room with Nicky and Alex they confuse the twins when Becky tells Jesse that he can take a break and try to get Alex to use the potty because he is doing the potty dance but the kid doing the dance and the one Jesse takes upstairs is actually Nicky. This is noticeable since Alex's hair is slightly lighter that Nicky's and his cheeks aren't as chubby as Nicky's.

Character mistake: In the scene where the twins erased Jesse's report, he first stated he just finished page 12. When the twins push a few keys it shows the laptop screen and it started with the top of the report and scrolled down maybe one page. The shot changed and the twins hit one more button. Shot changed back to laptop and it was at the bottom of the report, which if paid close attention from before when it scrolled one page down its the same words as before making the report 1 page long, not 12.
Character mistake: Danny and Joey finds out that their high school girlfriend was using them to make Jesse jealous. In season 1 it states that Danny is 30, and Jesse is 23, making Jesse 7 years younger. High School Danny would be 16-18, making Jesse 9-11 years old, and not in High School.
