- The series timeline: how did Adam go through three years of middle school (seasons 1 to 3) when he was said to be in seventh grade in the pilot? Even if we retcon this to say he was actually in sixth in season 1, we know that Erica had to be in at least tenth in season 1 because it's said that she dropped her "uncool" look following ninth grade, meaning that she should have graduated by the time that Adam enters high school.
- Some middle schools start at 7th grade and go to 9th while the high schools start at 10th.
- Its been stated more than once that Barry punched a horse and now he has a problem with all horses. Knowing Barry im sure he just over reacted but what did the horse do exactly?
