Rachel: I tried, but I don't have a gag reflex.
Emma: When you're older, that will turn out to be a gift.
In season two the show makes Dalton look like it's in a suburb of Lima. Dalton Academy is suppose to be located in Westerville, OH, which is two hours southeast of Lima. Kurt & Blaine would not be able to go to the "Lima Bean" coffee shop every day if this was the case.
The show is based on creator Ian Brennan's experience in show choir at Prospect High School in Illinois.
