Stephanie looked older than her age in the later seasons!
When she entered middle school, she looked and acted like she was at LEAST 2 years older than she was supposed to be.
In the smoking episode and the one where she got a date with the drummer boy, she was supposedly in 6th grade (11 years old). But she looked like she could've passed for 13-14.
During the last season, Stephanie, along with Gia looked more like 9th/10th graders than 7th graders. Just saying.
