Aidan has two faces.

When Aidan first came into being (way, way before he was ever JD's brother), I pictured this:


And Jared Padalecki is still "officially" the face of Aidan (with the personality of one of my coworkers)... but when I write I am secretly picturing Steven R. McQueen:


I think it is partially because Aidan's storyline has taken on a little bit more of a dark and emo sort of tone than I originally planned, which fits Steven's visuals better. Plus it's easier to picture him as the "helpless" baby brother since he's only like 20 whereas Jared Padalecki is like 30 now.
