Yeah I agree about Alyson, in the first season especially she looks soooo young. It's not really until season 3 of Buffy/American Pie time that she starts to look a little more like Hollywood's typical slightly older actress's playing teenage, and even then it's of super obvious the way it is with some actors. But in season 1 you could really buy that she was the same age as her character. And weirdly when she cut her hair for the flashback in Restless she still looked almost that young again!

For VM they had pics the actor playing Logan, but tbh he looked the same to me as a teenager as he did when he was 21 and playing Logan lol
