S5·E3 Beer Pressure

Julie starts dating an older guy named Jason. He continually encourages her to do more mature things, like stay out late on school nights. Because she's still a high school student and he's not, Julie feels like she can't say no because Jason will think that she's too much of a kid. While they attend a school dance together, Jason blows off the actual dance and ends up drinking in the hallway. When he's ready to leave and wants to drive Julie home, Kristy and Mary Beth don't think it's a good idea because he's been drinking. Julie goes anyway because she's afraid to say no. She and Jason end up getting into a car accident. Luckily, neither of them are hurt badly, but Julie injures her shoulder and can't play in Deering's game.
