Well, "being with the show" doesn't necessarily indicate "being Wendla in the show" since she was 13. She obviously started out as one of the ensemble kids and worked her way up, if she was the 3rd one to play the character.
(And I don't care anyway; I think Lea is talented but like what she's doing now, better. I didn't like the show. I liked Christine Ebersole in it when I saw it 3 years ago, though. I think she was the only "name" in it when I saw it. The kid who had played "Karl" on "Lost" had just left, also. Can't remember who played his role.)
"There is no use trying," said Alice; "one can't believe impossible things." "I dare say you haven't had the practice," said the Queen. "When I was your age, I always did it for half an hour a day. Why, sometimes I've believed as many as six impossible things before breakfast." --Alice in Wonderland
