"The characters are that vague TV high school age, but they'll be in high school as long as we need them to be"

This quote by Josh Schwartz is describing the characters in his television program. He is suggesting that the characters are of high school age, but they will remain in high school for as long as the show requires them to be. This suggests that the characters will not age or carry on to college or other phases of life, but will remain in high school for the duration of the show. This permits the show to stay focused on the characters and their high school experiences, without needing to fret about them aging or moving on. It likewise permits the program to stay relatable to its audience, as many audiences can connect to the characters' high school experiences. This quote also recommends that the program will be able to explore different stories and plot points, as the characters will stay in high school for as long as the program requires them to be.
